80416 RUM/8-59-1-9/24 Study of Uce Behavior of Constructions by Experimenting With Mockups From Plastic Materials at banding: 480 - 600 kg/aq am. The values of the elasticity module and flow, depend from the thermal treatment of the material. "SDP-2", "SDP-3" and "SDP-4" become white at tension and black at compression. The characteristics diagrams of the second and third varieties are very similar to the theoretical diagrams of Prandtl, being almost perfectly elastic for 6 -< a 0 and perfectly plastic for a a 0~ . (Figure 2) . The first experiment has been carried out within the Chair of Mechanical Constructions of the Institutul do Constructli. (Institute of Constructions) in Bucharest with the "SDE" plastic, by checking the frequency of the proper vibrations of a seven-story frame (Figure 4). 7be plastic mookup, has been built in a scale of 160. The concentrated masses have been re- duced to 1/40,000 and the time value scale was tm - - 4 tp. The ex- periments have proved that the hypothesis of the InfITFte rigid spare of' the frame is admissible. New'statical computation methode of tower can- struotions have been checked by another experiment [Ref 2), a~:oomplished with "SDE" material. By using "SDP-1" material, the moment of the appearance of the first plastic joint, the points of the appearance of the Joint, their order and the computation of the bearing capacity have Card 7/ 11 been checked by a frame (Figure 6), loaded symmetrically [Ref 2). Based 16 R W 8-59-1-9/24 Study of the Behavior of Constructions by Experimenting With Mockups From Plastic Materials on a computation of 0.1, Rozenblat [Ref 31, the appearance order of the plastic joint should be, as shown by Figure 6. According to the c&lcula- tion gf the first order, the breaking load Is P Ma 0 me W 103 kg. cm, P r " 777 r a' W.4 kg. AccoMing to Uie calculation of the second order [Ref 6]. the breaking load Is Pr w 72.6 kg. The real breaking load resulting from the ex- periment was 76 ks. The-results obtained from mockups can be used for the construction of normal size M N 1 1yl N I + 1.6 1 P . + P2 is equal for both, the model and the construction. Since this condition is not satisfied, there is no similarity between the mockup and the con- struction, which has an Influence only upon the bearing capacity-, The bearing capacity of the prototype Isl OL.

In case of a. metal prototype with & = 50, E - 2, 100,000 and T w 2 400, and a mockup of "SDP-1" with a 0 M - 550W*q cm, Em k.0;6 kg/sq cm, the following result is being ob- tainedi D m The experiment supplies the appearance points of the plastic joint, their ordar and the bearing capacity. Another experimental frame LRef 51 is shown by Figure 8. Two mockups have been made, the one fVom SDP-2 and the other from "SDP-3". The results are shown by the table on page 162.~ A series of experiments have been conducted with photo- elasticity. Photo astle mookups are made from "Dinox F-110", an optical active epoxy resin~produced in Rumania [Ref 61. The behavior of a girder with rectangular oles made of "SDP-I" and of Dinox F-1101' has been studied simultaneously'. The authors have examined: a) the bearing capacity; b) the influence of the oono*ntration of tension, in the hole Card 9/11 comers upon the bearing capacityj a) the regions of entrancer into the q1 8*1k IRWV8-59-1-9/24 Study of the Behavior of Constructions by EMerimenting With Mookups From Plastic Materials plastic zonej d) the coincidence of these regions with the maximum stress, resulting from the photoelastic mookup.

The experimentation w1th mookup Nr 1 has proved that the lose of the bearing capacity of the bar was due to the unitary forces of tension In the lower section, In the region of the two central solid sections. Figure 12 shown the distribution of the tension in the elastic field. Accomplishing the calculations, P - 112 kg, at which the plastifi- cation has appeared, thus resulting for the "SDP-1" mockup: CF - 530 kg/aq cm. The calculation of the unitary tension force has been accomplished by con- sidering the value of the material bandt T 0 1 - 5.25 kg/sq cm/cm. The thickness of the mookup from "Dinox-110" was 5.5 mm and the power by which the Isochromatio table has been established was P - 18.7 ks, The maximum tension has appeared not In the mainly stressed middle section but in the solid section. The experiment with mookup Nr 2 has proved that the loss of the bearing capacity was due to the shearing of the solid section (see Card 10/11 Figure 11). Regarding the bearing capacity, the loss has been produced at 80416 RUM/8-59-1-9/24 Study of the Behavior of Constructions by Experimenting With Mockups From Plastic Materials the mookup Nr 1 at P - 125 kg and at mockup Nr 2 at P - 100 kg. Other experiments have been conducted with a curved bar exerted to horizontal symmetrio forces (Figure 15) and a frame exerted to a horizontal force. Plutic materials allow a study of a wide range of problems, regarding the kind of loss of the bearing capacity. Chromoplasticity makes the, direct detection of plastic deformation zones possible which cause the rupture. The experimental results have been checked by theoretical cal- culations and photo-elastical experimentations. Chromoplastic experiments are very simple and can be accomplished without special devices, except the load arrangement. There arse 22 photographs, 2 diagrams, 2 graphs and 6 references, 5 of which are Rumanian and 1 Russian.

For this purpose, the activation energy was calculated on the basis of the multiplet theory (Table 1). The average value found for theadeorption potential of hydrocarbon dehydroge- nation was 51-5 for beryllium,oxide, 70.7 for magnesium oxide, 116.2 for zinc oxide, and 132 .3 kcal/mole for cadmium oxide.

The intermediate mechanism in the temperature ringe of 6ooo - 7500C is a polycondonsation of products of the catalytic dehydra- tion of alcohols (propylene, hexylene,*cyclohexone). Possibly, a poly- condensation of ethylene takes place likewise under these conditions, but since the rate of this process is too low, it occurs only at higher temperatures, in the course of the high-temperature mechanism. The following scheme is offered for the intermediate mechanism: Card 2/5 Carbon Formation in the Decomposition of 3/062/60/0001011/003/016 Isopropyl Alcohol, n-Hexyl Alcohol, and B010078 Cyclohexanoi on the Copper - Silica Gel, Catalyst polyoyclic saturated, un- _H20 _H2 etc. saturated, and aromatic b hydrocarbons of different loat&lyticT 7olycondenz density degrees, up to dehydro- sation carboids genation I I The replacement of the intermedJate mechanism by the high-temperature mechanism manifests-itself by a marked retardation of the process at temperatures above 75000- In thi range of 7500 - 8750 the carbon forma- tion is slowed down, after which it is again speeded up vigorously beyond 875OCw' This mechanism (7500 - 950 C) comprises the following processeel polycondeneation of decomposition products of the alcohols used (lowest paraffins and ethylene)l polycondeneation of aromatic hydrocarbons, resulting from the decomposition of alcoholal polycondensso- tion of the alcohols used.

X-ray analy- sis of the catalyst prepared from titanium tetrachloride showed It to be anatase. The iransformation of isopropyl alcohol on TiO 2 was accompanied by a marked change in thermal effect during the first 15-20 min(Table 1, Fig-3a). The analysis of the gaseous products formed in the reaction showed that. the alcohol is practically only dehydrogenated durin3 the first 7-8 min. After this period dehydrogenation and dehydration take place simultaneously and after 15-20 min dehydration occurs alone. From a comparison of the thermocouple data with the analytical data of the reaction products and t!ie degree of carbon deposition on the catalyst surface it can be seen that the rates of dehydrogenation and dehydration, and the carbon content of the surface run parallel. The change in selectivity at otherwise unchangel general activity of TiO2 is probably due to the accumulation of carbon on the sur- face. Deposition of carbon on the surface of Cr 203 (Fig. 3b), however, W4S found to have no effect on its activity and selectivity. Summarily, the Card 2/3 Investigation of Catalytic Transformationn of SIG621601000101210021020 Isopropyl Alcohol and Cyclic Hydrocnrbons B013/F055 on Titanium Dioxide (Anatase) Using a Differential Thermocouple authors conclude that a gradual accumulation of carbon on the unatase our- face almost entirely suppresses the dehydrogenation of the alcohol and promotes its dehydration, but does not affect the total activity of the catalyst. The catalyzed irreversible transformation of cyclohexene and cyclohexadiene is suppressed by the accumulation of carbon on TiO., wherens the dehydrogenation of cyclohexene, cyclohexane, and cycloboxadione in pro- noted by this process.

For ethyl and n-butyl alcoh4 the apparent activation energy of dehydration is 30 koal/mol Is , for isopropyl. alcohol, 24 kcal/mole and for tert-butyl alcohol, 16 kcal/mole. The true activation energies of alcohol dehydration (isopropyl and butyl alcohols) were determined, at 26.1 kcal/mole for isopropyl alcohol and 33.4 kcal/mole for n-butyl alcohol by means of the kinetic equation by Balandin (Ref. 20). The relative adsorption coefficients of the dehydration products from n-C,H OH and ito-0 H OH as a function of temperature are given in Tab 965.

The specific reaction with which the authors were concerned was to prepare 2-isopropylanthraquinone in two sta- gest instead of four as in Scholl's method, which involved react- Ing isopropylbenzone with phthalic anhydride and reducing the re- sulting 4-isopropylbenzoyl-2-benzoic acid to 4-isopropanyl-benzyl- 2-benzoic acid followed by cyclization of the Intter in the presen- ce of sulphuric acid, To avoid the formation of sulphonic acid Card 1/3 27126 S/080/60/033/008/019/022/XX Method of preparing D213/D305 derivatives and to increase the yields of the required quinone the authors investigated the influence of the oleum concentration, tem- perature and period of heating, In the case. of 3 % oleum and heat- ing for I - 3 hours sulphonation occurred., When the concentration was increased to 8 % the yield of quinone was 15 %; however, this yield decreased when 12 - 20 % oleum was used. The effect of heat- ing with 8 % oleum is shownt and it is clear that the time of re- action determines the yield of quinone. Beut results were obtained with reaction times of 2.5 3 hours, and under optimum conditions the yield reached 55 - 60 In the earlier investigations the first stage, condensation of phthalic anhydride with ieopropylben- zene, was conducted in a carbon disulphide medium, The authorst however, used chlorobenzene as a less hazardous solvent and achie- ved 88 % yields of 4-isopropylbensoyl-2-benzoic acid. The quinone obtained in the present work had a melting point of 56.5 - 57.00C9 (recrystallized from alcohol) as compared. with 450C given in the literature. The composition and properties of the resulting pro- duct corresponded to those of isopropylanthraquinone, The quinone Card 2/7 27126 8/080/60/033/008/019/022/XX Method of preparing D213/D305 obtained in both the laboratory apparatus and the model plant had a malting point of 560C and its 0 and H contents corresponded with the fQraula 017H14 02* The use of isopropylanthraquinone an a hy- drogen transferring agent was studied by hydrogenating the compound in the presence of a skeletal nickel catalyst until a thick mass of 2-isopropylanthrahydroquinone was formed. After separation the catalyst the product was oxidized with air and the hydrogen peroxide formed Was removed with water, A similar reaction has been found to proceed with 2-othylanthraquinone. In both cases the melting point of the material recovered corresponded to that of the original quinone. There are I f:Lgure, I table and 2 non-Sov- let-bloc reference.

TITLEs Ca.talytic Decomposition of Di-n-butyl Sulfide on 0~.-Fa PERIODICAL: Zhurnal fizicheskoy khimii, 1960, Vol-34, No. 9, pp. 2030 - 2040 TEXT: It was the purpose of the present work to carry out a multi-purpose investigation of the procoss of decomposition by means of kinetic, thermo- magnetographic, radiographical and chemical analyses for the purpose of explaining the mechanism of the desulfurization on contacts containing reduced iron by the example of the catalytic model reaction. The catalytic and thermal conversion of Di-n-butyl sulfide and n-butyl mercaptan wns studied with the help of a flowing-through method in a device used in the authors' laboratory. It was found that the sulfide decomposes thermally at temperatures of more than 4000C. The kinetics of the catalytic decom- position of the sulfide was studied at 300 - 4000C, where 8 r.1 reduced aL-iron in a. 6.5 cm thick layer was used at a feed rate of the substance of 0.18 ml/min. The experiments took 45 - 50 minutes.

For the purpose of displacing the initial mnt~~rlal and the decomposition products from the reaction zone, nitrogen was blown through, and the catalyst was regerertited with hydrogen at a temperature that was 500C above the experimental temperature, with the result that H2S was evolved. The compoaition of the gaseous decompouition products is given in Table 1, from which it may be seen that unsaturated and saturated hydrocarbons (up to 17 as well as F2 were liberated. H 2S is formed after a longer time of contact, If the activity of the catalyst. is highly, and the decomposition of the sulfide is little reduced. Other sulfur-or anic compounds are not formed. Fig. I shows log I as a function of I/TtP, from which the apparent activation energy E is calculated as amounting to 12.7 kcal/mole. The results of the hydrofenation of Di-n-butyl sulfide on ck-Fe are given in Table 2, and the composition of the gases, determined by the low-temperature rectifying apparatus QHATIIM-r)l (TaIATIM-51) are given in form of a summary. The results obtained by means of a catalyst poisoned with sulfur at a hydro,onolysia of the Di-n-butyl sulfide at 430 - 4800 are given in Table 39 whorc It was found that Card. 2/4 Catalytic Decomposition of Di-n-butyl S/076/60/034/009/030/041XX Sulfide on d,-Fe B02O/BO56 sulfidized o~-Fe hydrogenizes sulfides more slowly at higher temperatures, which may be seen from the values of the activation energy. Fig. 2 shows the thermomagnetogram of d.-Fe, upon which Di-n-butyl sulfide was decom- posed at 300 - 4000, whereas Fig. 3 shows the change in magnetization with the temperature for a catalyst, which had been poisoned with mercaptan at 2700 and did not decompose the sulfide. When this catalyst was brought into contact with Di-n-butyl sulfide at 430 - 4800, a further accumulation of sulfur was found to occur (Fig. 4, curve 0, where a maximum occurs at 2000, and at 2800 magnetization. vanishes. Nhen cooling the specimen# a sharp rise of magnetization is found (Pig. 4, curve 2). Table 4 shows the results obtained by X-ray structural analysis. By the catalytic decomposi- tion of the sulfide and mercaptan, also compounds FeS 1+X are formed, where x< t. The effect produced by these compounds upon the desulfurization is investigated on N-Fe by means of carbidization and sulfidization tests, where the apparent activation energy of the sulfidized catalyst equals 19.7 kcal/mole. On the basis of the multiplet theory, schemes (index groups) for the decomposition of sulfur-organic compounds and hydrogenolysis were suggosted, which are confirmed by data from publications and the results obtained here.

The data listed in tibl; I Indicate that the apparent activation energy, Q, calculated from the Arrhenius equation, and the relative adsorption coefficient, %2, of the benzene being formed are greatly dependent on the nature of the carrier substance. These two quant Ities are interrelated by Q - I - k10922 (I and k are constants). This relationship Is graphically represented in figure 1. For all catalysts under consideration it was found that E.was constant and 14 koal/mole approximately. This value cor- responds to the initial coordinate of the straight line depicted in figure 1, and thus represents the true activation energy.

The experiments were conducted according to the continuous method on a mixed-oxide catalyst (Ref. . The substance used for dilution was water vapor (w 0ight groportion of la2~)- Before the reaction, the water vapor was overheated to,300 . The nontents Of C02, unsaturated and satu- rated hydrocarbon and hydrogen were determined in the gas obtained after the reaction. The catalyeate was colorless. A far-reaching agreement was observed between the amount of liberated hydrogen and the developing a-methylatyrong (Table 1). For 30 min a mixture of air and water vapor was blown through the catalyst afters each experiment, and thus the activity of the catalyst was maintained. The kinetics of the above reaction was investigated at 5000-5500 with a Passage Of 0.42 ml within 3 min. The latter eorresponded to a volume Card 1/3 Catalytic Dohydrogonation of Isopropyl.

The contact gas mainly consists of hydrogen with 0.5% to 2.0% Of C02, and contains up to 0.4% of unsaturated, but no saturated hydrocarbons (Table I). The constants of the reaction rate were calculated from the obtained data according to Ref. 7 on the basis of equation (1) In such a way that they can be used under the conditions of a continuous system.
