ABSTRACT It was recently found that isopropenyloyclopropane at room temperature in the presence of palladium black absorbs 2 hydrogen molecules and forms 2-methylpentane. The reaction takes place with an Intermediate formation of 2-methylpentane-1 &-A -2. A scheme is given. Isopropylcyc_ lopropane does not form at all under theses conditions. This peculiar behavior of isopropenyl cyclopropane gives rise to the supposition that the double bond existing in the side-chain weakens the stability of the C-C bonds of the three.-member ring which lie near the substi- tuent against their reactions of splitting and addition to hydrogen. This apparently takes place thanks to a peculiar conjugation between the cyclopropane ring and the double bond. The hydration of the mention- ed substance in the presence of platinum black takes place in a diffe- rent manner: 1,3 mol. of hydrogen are absorbed and a mixture of 70 0/0 isopropylcyclopropane and 30 '0/0 2-methylpentane develops. Tn this czze., therefore, the splitting 9f the three-member cycle under addition ot Card V4 hydrogen according to the palladium scheme takes place slowlier than 20-2-29/62 The Hydration of Vinyloyclopropame and 1-Methyl-1-15ohexanyl CycloP70- pane in the Presence of Platinum and Palladium the addition of hydrogen to the double bond with retention of the propane ring, In the first reaction 0,6 mol-, for the second one 0*7 mol. of hydrogen are consumed. The present work studied the additic..~n of hydrogen$in the presence of the blacks of both metals, to two other hydrocarbons of the cyclopropane aeries which contain a double bond in the side chain (see title). With palladium black (at +20C) vinY!cYclo- propane readily absorbs 2 hy&ogen molecules and forms n-pentane. That means that here the three-member ring, under addition of hydrogen, is split just as easily as in the case of isopyopenyl cyclopropane, the double bond of the side.chain being hydrated in this connection. If the hydration is interrupted and only 1 H-molOcule is permitted to add) a complex mixture develope.whilch is not yet thoroughly investigated- it room temperature wit1kAV1at1n'um'b`J&ck or at 100 u C with a copper- -chromium catalyst and up to 130 at. superpressure 1-methyl-isohexanyl, cyclopropane is converted t6 1-methyl-l-isohexyleyclopropane which was hitherto not described intpublications.

The following -oxplanation Is given for that: Fatt of the added hydrogen AM consumd in the hydration of the double bond in the side chain; the rest is used for the addition to the isomeric by- drocarbon in which the d6ublebond, under the influence of palladium- black, had shifted into a conjugate position with the cyclopropane rings 1-methyl-isoheianyloyclopropahe, produced due to isomerization,, with a conjugate position of the double bond in relation to the cyclo. propane ring apparently should behave analogously to vinyloyclopropane and isopropenyloydopropans in.the presence of palladium and hydrogen. Namely it should absorb 2 hydrogen molecules and be converted to 2,6- -dimethyloctanee In the presence of platinum black the double bond doeo not shift. Therefore the hydration result is only 1-methyl-l-isohexyl- cyclopropanso At 1600C this latter is converted to 2.,2,6-trimethylbap- tane in the gas phase and in the presence of platinum-plated charcoal under addition of hydrogen* Thorefore the hydrogenolysis of the 3-aem- ber ring here occurs in the earn manner as in the case of other alkyl- cyclopropanes, namely under a splitting of the C-L bond lying opposit( Card 3/4 to the substituent, Experimental part with the usual data.

When the dealkylation actually proceeds according to an ionic mechanism, a connection is to be assumed to exist between the above-mentioned chano ge and the modification of the olectronic density of the benzene nucleus, as a whole, and with the electronic rediatribution according to the nature and the orientation of the second substituent. The au, thors considered it timely to carry out a more systematic investigaw tion of several alkylaromatic hydrocarbons, together with derivatives,, with one and the same catalyst and lander comparable conditions with regard to their speed of dealkylation. Table 1 shows the eleven sub- stances selected for this purp-:,s,~. The quartz tubes with one of these substances respectively were exposed to a temperature of from 37o to 49oOC in an electric furnace with a thertnoregulator. The test result-,; were worked on according to the equaticn by Frost for -nonomolecular, heterogeneous reactions in a pEzsage system, when these reactions are hindered by transformation products. The apparent constant's of rea~-tion speed were calculated and the apparent activation energies were deter= mined from them on a graphical way (table 2).

The data for alkyloyclobutanes lack. G',clopropane was more able to bind hydrogen to palladium on pumice at hiaher tem- peratures than to platinum. The results dtained in present paper (and in the title) are easily to be compared to those on platinized coal. The experiments have shown that ethyloyclobutane can be hy- drogenolyzed on palladium charcoal at a somewhat higher temperature than on platinized charoo9l. Here also the two possible bindings of the 4-part cycle were cracked, however, a branched isomer was produced in a somewhat greater quantity (60%). Considerable dif- ferences ftm the platinized charcoal were found in the case og 1,1,2-trimethylo3olopropane. It was proved that at 100 and 120 both possible reactions of hydration took place: hydrogenolysis as well as isomerization with a subsequent hydration. Thus the catalyzate contained gll 3 possible products of the fission of the 3-part cyc- le. At 220 the secondary reaction took placc to a greater extent, and the mixture of 20-dimethylbutane and 2-mothylpentane amounted Card 2/3 to already 40 % of the -total mixture.

The object of investigation in this case was 1,1,2-di- nethylcyclopropane. The above-mentioned palladium- and platinum- -chazcoal served as catalysts. The investigation performed in thin manner showed that palladium-plated and zionpalladium-plat- ed charcoal at a temperature above 2000 C causes a marked i2o- merization of 1,1,2-dimethylcyclopropane to olefins. This iso- merization occurs more actively on a rise of temperature to Card 112 2500 C and its depth remains constant on a further rise of The Isomerization of 1,1,2-Trimethylcyclopropane in the Presence 62-58-3-7/30 of Palladium- and Platinum-Charcoal temperature to 2800 C. An analysis of the product of catalysis showed that the isomerization in the presence of both catalysts approximately occurs with a 60% yield. On that occasion the lin1kage between the carbon atoms of the cycle which were hydro- genized least and those which were hydrogenized most strongly breaks, which is in agreement with experience. But the authors also could determine another direction of the occuiring tear at the expense of the bond at the tertiary carbon atom. A scheme on the reaction of the isomerization, is given on page 301. There are 4 tables and 10 references, 8 of which are Soviet. ASSOCIATION: Institut organicheskoy khimii im. N. D.

The quantitative relation of the components depends on the reaction conditions. In the present paper the relia- bility of the three bromimetric methods - aocording to Rosenmund (Reference 3), Gallpern (Reference 5) and Vyrabiants (Reference 6) is examined. This control was investigated in pure C -hydrocarbons and also in various artificial. mixtures of iso~entane with isopentenes and isoprene shich differed in the number of components and also in their concentration. It Card 1/5 became evident that the method according to Vyrabiants is not 75-1-23/26 BromOmetric Methods of Determining Unsaturated Hydrocarbons in Isopentane- Isoprene-Iaoamylone Mixtures suitable for an analysis of such mixtures, because the error assumes different values and attains up to 7 - 8 ~~10 (absolute). The results obtained according to Rosenmund and Gallpern conv firm the fact that the accuracy of the determination of double bonds depends on the structure of the hydrocarbons and on the -composition of the mixture; 2-methyl-butene(2) and 3-methyl- butene(l) without difficulty absorb 1 bromine molecule on bromination. 2-methyl-butene(l) and isoprene consume more than 1 bromine molecule and therefore yield too high results, relative to a double bond, in the determination according to Roserunund and Gallpern. The analysis of mixtures with 3 or 4 components, but without isoprene, showed an average absolute error of the determination of the olefines of + I %. On addi- tion of iso.Drene to the mixtures with 3 components the ab- solute error increases to + 3 %. The analysis of mixtures with 5 components showed that t7he absolute error in the case of an isoprene content up to 20 % in the method according to Rosen- mund on the average amounts to + 3 ~~ and according to the Card 2/5 method by Gallpern -2 As the average error in the 75-1-23/26 Bromometrio Methods of Determining Unsaturated Hydrocarbons in Iso- pentane-Isoprene-Icoamylene Mixtures determination of the total number of double bonds in mixtures of 5 components according to both methods has a systematic nature, it can be taken into account by the intro- duction of a corresponding coefficient (in the case of an isoprene content up to 20 %). It was shown that the values for the total number of double bonds which were once de- termined according to Rosenmund and once according to GalXpern practically ooincide after the introduction of a correction coefficient. As the method of bromination only makes possible a sum determination for alkenes and dienes, the content of monoolefines can only be determined from the difference between the total number of double bonds and the content of dienes. In the present case an appropriate cor- rection which takes into account the content of isoprene must therefore be applied to the bromimetric results for determin- ing the content of isopentenes. For the determination of iso- prene the photometric method according to Robey and Wiese (Reference 17) was employed which is well applicable in the Card 3/5 presence of monoolefines, but also of some dienes. The average 75-1-23/26 Bromometric Method of Determining Unsaturated Hydrocarbons in Isopentane-Isoprene-Isoamylone Mixtures error of this determination is less than 1 51 (absolute). Determination takes 1 1/2 hours, which time can be shortened in series determinations to 20 minutes for one determination. When the concentration of isoprene in isopentane-isoprene- isopentene mixtures has been determined in this manner, the content of isopentenes (P) can be calculated according to the formula P - a.Pl-b. P is the found total number of double bonds in the mixture, b is the concentration of isoprene in the mixture and a is the correction coefficient. In the method according to Rosenmund a - 0,96 and in the method aecording to Gallpern a - 1,04. All performed testa are exactly de- scribed. During the elaboration of this method a short article by Timofeyeva and collaborators (Reference 18) on the same problem was published. In this article a correct-ion co- efficient is introduced in the final formula of the calcul- ation which only takes into account the error produced by the Card 4/5 inexact bromination of iBoprene. 75-1-23/26 Bromometrio Methods of Determining Unsaturated Hydrocarbons in Isopentane-Isoprene-Isoamylene Mixtures There are I figure, 5 tables, and 21 references, 15 of which are Slavic.

In this connection special attention is payed to those publications which are edited by V. D. Zelinskiy, his collaborators and otudents (Refs 1-50). As may be seen from the present paper the current investigations of the mineral oil fractions until the years 1937, 1939 were carried out mainly in connection with a chemical characterization of the light benzoin and benzene ligroin fractions of mineral oil. Only in the 1940's methods were elaborated for the intensification of the individual investigation. of the light fractions of the Soviet mineral oils. Card 0 At the beginning of thi3 paper reports are made on the first SOV/74-27-10-1/4 Investigation of the Composition of the Light Fractions of 1.'j.-Soviet Crudes work carried out in 1881-83 (Bellshteyn and Kurbatov). The diverse research institutes of mineralogy which have been established are chronologically mentioned (e. g.: 1924: the first central (Gosudarstvennyy Issledovatellskiy neftyanoy Institut) State Research Institute of Petroleum - in Moscow); 1934: In- stitut goryuchikh iskopayemykh AN SSSR (Institute of Combustible Minerals AS USSR), diverse chemo-technical laboratories of the GINI (State Research Institute of Petroleum) as well as diverse research institutes in the Republics of the Uhlon: Azerbaydzhanska3 SSR, Vzbeks"ya SSR, "TuAmeliskay& SSR, and others. After 'World War 11 methods of group analysis on a higher level were elaborated for the investigation of the petroleum naphtha fractions (with a further differentiation of the hydrocarbon sub- groups). It was necessafy to investigate in detail the compositiol of the hydrocarbons of the light mineral oil fractions because of the rapid development of air plane and automobile motor construction in the USSR. Due to this fact the demands concerning the quality of the motor fuel as well as of the crude oil changed Especially in 1955 intensive investigations of the individual composition of the hydrocarbons of gasoline produced'by crackinC Card 2/1~ were carried out by using the chromatographic distribution of SOV/74-27-10-1/4 Investigation of the Composition of the Light Fractions of Soviet Crudes adsorption, the catalytic analytic hydrogenati(,n and dehydro- genation as well as spectrum an&ly31s by means of combined dispersion of light (Refs 108-160). In conclusion the authors are of the opinion that mere geological and geochemical factors are not sufficient for the production of experimentally founded theories on 'the formation and the change of petroleum under the conditions of migration. A great number of important data are necessary for the solu%ion of the problem of the formation of petroleump, namely the riature, the concentration and the composition of the hydrocarbon components (or the non-hydro- carbon components); i. e., of'the organosulfuric, nitrogen and oxygen compounds which belong to the composition of petrole- um. , There are 160 references, 160 of which are Soviet.

On the Limited Applicability of the Auwers-Skita Rule in Stereoisomeric Dialkyl Cyclanes (Ob ogranichennoy primenimoati pravila Auverea-Skita k stereoizomernymdialkiltsiklanam) PERIODICAL: Doklady Akademii nauk 833R) 1958, Vol 122, Nr 6, pp 1025-1028 (USSR) ABSTRACT: In recent years it was repeatedly noticed that the rule mentioned in the title cannot be applied to 1,3-dialkyl cyclopentanes and 1,3-dialkyl cyclohexanes. In these latter series the interrelation of the properties of cis-and trans- -isomers is reversed. By the example of the stereoisomeric lt3-dimethyl cyclopentanes and 113-dimethyl cyclohexanes tnis statement was confirmed by thermodynamic data as well as by synthesis. Recently the authors have observed ouch a case in which a peculiar deviation from the same rule took place (Ref 1) in the 1,4-dialkyl cyclohexane series. In this series the applicability of the rule under consideration was Card 1/4 denied by nobody. It became evident that in the case of the 4 On the Limited Applicability of the kuwera-Skita SOV/20-122-6-19/49 Rule in Stereoisomeric Dialkyl Cyclanes stereoisomeric 1,4-diisopropyl cyclohexanes the specific weight and the refractive index are higher, thi molecular refraction, however, and the malting temperaturi of the isomer boiling at a lower temperature are lower; the spectroscopic data have shown that the lattir isomer is a cis- -form. So in this case not the trans- but the cis-form has a lower boiling-point - contrary to the rule mentioned. The observations so far collected make it possible to approach the problem of the relations between the configuration and the physical constants by a new methodl the applicability of the rule mentioned is not only restricted by the arrangement of the side chains in the dialkyl-cyclane molecule, but also by the atomic number of carbon in the latter. The authors believe that the deviation described above is a regular phenomenon. The reflections mentioned make it possible to conclude that stereoisomerie 1,4-dialkyl cyclohexanes with 12 or a few more carbon atoms in the molecule mustsimilar to 1,4-diisopropyl cyclohexane, deviate from the rule under Card 2/4 consideration. Thus the Auwers-Skita rule is only applicable 8j;P On the Limited Applicability of the Auwers-Skita SOV/20-122-6-19/49 Rule in Stereoisomerio Dialkyl Cyolanes to the first members of the series of the 1,4-dialkyl cyclohexanes. By studying own data and those mentioned in publications on boiling temperatures of the atereoisomeric dialkyl cyclan"as it can be concluded that the linear character of the dependence between the differences in boiling temperature of the stereoisomers and the atomio number of carbon in the molecule is not confined to the 1,4-dimethyl cyclohexane series, but applies also for the 1,2-dialkyl cyclopentanes (Table 2 and line A of Fig 1). In the st ereoisomeric 1,2-dialkyl cyclanes discussed here the boiling temperatures of the trans-form increase more rapidly with increasing molecular weight than in the cis-forms. In these cases, however, the Auwers-Skita rule must have a somewhat wider range of applicability than for 1,4-dialkyl cyclohexanes.

They concern the direction of cleavage of the 3-membered ring. Most of the authors assume that the linkage between the two most hydrogenized carbon atoms (Refs 1-6) is being cleaved under a hydrogen affiliation (I). But there are also cases described of a ring cleavage in other directions (II) (Refs 7-9). Ya. M. Slobodin and coworkers (Ref 9) conclude that an intermediate stage of isomerization of the alkyl cyclopropane to an olefin is interpolated; the olefinafterwards Card 1/4 being hydrogenated. The existence of an olefin in the products Effect of the Nature of the Carrier Exerted on the SOV/20-123-1-28/56 Direction of Catalytic Hydrogenation of Hydrocarbons of the Cyclopropane Series of an incomplete hydrogenation was proved by the Raman spectra. Reference 9 does not present any definite causes of the various cleavage directions of the 3-membered cycle. There is, however, one important factor which is capable of affecting thementioned direction of cleavage, viz. the carrier of the hydrogenating metal, in so far as the employed catalysts are mostly used on carriers. As was previously proved by B. A. Kazanskiy (Refs 10, 11)p silica gel and activated charcoal are able to catalyze the isomerization of cyclopropaw hydrocarbons to olefins. It was but natural to assume that the hydrogenating metals, if they are applied on carriers which are able to cause isomerization resembling the two just mentioned cases, will lead under suitable conditions to different cleavage direction of the ring than this would be the case with inert carriers. Actually, in the first case that olefin is hydrogenated which is formed in the ioomerization of alkyl cyclopropane (equation III); in the second case, the cyclopropane hydrocarbon itself will bo hydrogenated (equation I). The relative isomerizing activity of such catalysts on carriers will thus Card 2/4 determine the cleavage direction of the 3-membered ring. Effect of the Nature of the Carrier Exerted on the SOV120-123-1-28156 Direction of Catalytic IlydrQgenation of Hydrocarbons of the Cyclopropane Series In the present paper the authors describe tests concerning the isomerization of cyclopropane hydrocarbons to olefins in the presence of: aluminum silicate, kieselguhr and Pumice. On aluminum silicates, ethyl cyclopropane was nearly completely isomerized to a mixture of olefine of normal structure already at 500; on kieselguhr, to 75 ~a at 1200, on pumice at 1200 no isomerization occurredionly at 1700- 20 c,", were obtained, then at 2200 - 45 %. Thus, the influence of a carrier being active as regards isomerization exerted upon the direction of the hydrolysis of the 3-membered ring is unquestionable.

The attachment in thii 1.2-'-and 34-Positions is favored by the larger number of alkyl groups in the lat and 4th terminal carbon atoms (di-isocrotyl and 2-mothyl-hexadiene- 2-4): the alky! groups at the 2nd and 3rd atoms of the conjugate system have the same effect with regard to the 1.4--position (isoprene ard di-Laopropenyl).

It has recently become clear that the amides are capable of catalysing the displacement of the double bonds in mono-and diolefin hydrocarbons (Refs 7-10)- Consequentlyp it could be expected that under certain conditions the structure of mono-olefins resulting from the attachment of a hydrogeii molecule to the dienes should depend, not only on the structure of the initial. diene, but also on the secondary reaction of the iaomerization under the influence of the resulting metal amide. In order.to eliminate the isomerizing effect of the metal amide, ethyl alcohol was added tDthe sodium solution in liquid ammonia (Ref 11). Besides, di-isopropenyl was reduced by calcium-hexa-.ammoniate, and di-isocrotyl was reduced by sodium in liquid Ammonia (Ref 2). The results are shown in table 1. From this it can be seen that on the reduction from all its sources at the moment of its liberation, hydrogen is attached almost exclusively in the 1-4-Position of di.-isopropenyl, The reduction of di-isocrotyl is less selective, although hydrogen is attached here in the Card 2/3 1.2-positions.

Such mixtures are formed on dehydrogenation of isopentane into isoanylenes and isoprene. Their analysis was complicated and required much time (Refs 1-4). The authors successfully used a combination of two clLromatographic methods: the partition chromatography (Ref 5) and the "chromathermo6raphyll (Ref 6). The methods were worked out on pure individual hydrocarbons and on their artificial mixtures. The universal "chromathermograph" was used for the analysis (Ref 7).

This binary nixture was separated with respect to aluminum oxide using "chromathermography" (Fig 2). The results were of satisfactory accuracy. The deci- phering of the initial curve is of considerable importance in analyses of this type, Varimm methods are used for this purpose (Refs 3,9). Thero are cases of an incomplete sepira- tion of the components of the inixture. A method of calcula- tion for the solution of this quastion"Ref 11) is sugi;ested.

The investigation was performed accord- ing to the kinetic method and under conditions comparable for all 6 hydrocarbons. The experiments were carried out in the temperature range of 330--4900 (for ethylbenzene of 490-5500) and at different time of contact between the reacting substances and the cataryst,.

It was found that the depth of dealkylation under other- %vise equal conditions depends on the position of the methyl group with respect to the inopropyl jroup. The influence of the position of the second substituent in the lenzene nucleus upon the depth of dealkylation of eymenes was determined only qualitatively and by a few experiments. For this reason the behavior of 3 isomeric eymenes during catalytic cracking on Card 1/4 the synthetic aluminosilicate catalyst was investigated.

Kinetics of Dialkylbenzenes Dealkylation In studying the contact-transformntions of o-, mvp and p-cy- menes it was seen under given conditions that the principal reaction was the separation of the isopropyl group, toluene and propylene beinj formed.

In addition to the principal renction also side reactions take place such as redistribution of hydrogen, polymerization and isomerization, But as well as in the case of monoalkylbenzeneB their significnnce is small and concerns only tho separated isopropyl ginup. Toluene remains practically unchanged and may be regarded as an end product of the cracking of eymenes. The kinetics of dealkylation is well defined by the equation of Frost (Refs 8,9). On the basis of the data obtained at different temperatures and time of con- tact between the reacting substanceo and the catalyst the apparent rate constants of dealkylation and, therefrom, the apparent ener,gies of activation were computed (Table 1). For comparison also the data regarding the dealkylation of iso- Card 2/4 propylbenzene are given (also Fig 1).

Otdeleniye khimicheskikh nauk, 1959, Nr 3, pp 553-554 (USSR) ABSTRACT: This is a brief communication on the experiment to determine the influence exercised by the conjugated double bond on the stability of the three-membered cycle during the isomerization. It is known that alkyl cyclopropaneu isomerize relatively easily under the action of a series of catalysts and pass into an olefin mixture (Refs 3-5). The authors used kieselguhr for their investigation because in its presence ethyl cyclopropane is isomerized almost completely at 1200 (Ref 5). Tte experimenis carried out with vinyl cyclopropane under the same conditions have shown that quite unexpectedly no piperylene was present in the catalyst. With the exception of the first few drops the catalyzate showed constants of the initial hydrocarbon and pro- Card 112 duoed no adduct with maleic anhydride. At 1500 not more than ----------- Isomerization of Vinyl Cyclopropane in the Presence of SOV/62-59-3-29/37 Kiese1guhr 10 % of diene were observed in the catalyzate. It was jbvious to assume that vinyl cyclopropane is more reaction-;resistant than ethyl cyclopropane. This was, however, refuted-in the course of further experiments. It was found that the three- membered cycle which is conjugated with a double bond may be isomerized in the presence of kieselguhr. The degree of stabili- ty of the cycle in this case cannot be determined according to the amount of the forming piperylene since the latter completely poisons the catalyst.
