The Effect of Organic Catalysts in the Preparation of Sodium Hydride "On the Preparation of Sodium Hydride," by V. I. Mikheyeva, T. N. Dymova, and M. M. Shkrabkina,; Moscow, Zh.urrtel Neorganichesko Khimii, Vol >+, No >+, Apr 59, PP 709-7->-i A method has been developed for the synthesis of sodium hydride from the elements based on the application as catalysts of small quantities of mineral oils and of their aromatic fractions. Intensive agitation of the reaction mixture is employed. Of the substances tested for their effectiveness as catalysts (anthraaene, fluorene, phenanthrene, solidol, mineral oils and their fractions), the benzene-aromatic fraction of mineral oils wa,s found to be best. By using the method described, sodium hydride, which is 97~, pure, can be obtained. The procedure developed i;s recommenced . for application on an industrial scale. An attempt is made to explain the activating effec+, of the aromatic fraction of mineral oils ?~oi~ t:he reaction of the hydrogenation of sodium. It is pointed out that development of the chemistry of inorganic hydrides and of complex boro-hydrides depends on the development of cheap methods for the production of simple hydrides,? specifically sodium hydride.

The natural gas is converted to synthesis gas for the production of methyl alcohol and isobutyl alcohol. The process is completely automatized. These are the first converters in the USSR which operate on pure oxygen. "Production processes are being automatized by the Lisichansk chemists on an extensive scale. The process of the produc~t;ion of ammonium nitrate has been fully automatized. Automation of this particular depart- ment has resulted in a saving to the combine of more than a million rubles per year. The production of isobutyl oil by distillation has also been automatized.

'~orsunsldy, Chief Specialist, State Scientific Technical Committee at the Council of Ministers USSR; Moscow, Prom shlenno-~konomieheskaya Gazeta, Vol 4, No 59 (51~+), 22 May 59, p Recently, considerable progress has been made in the polymerization of aldehydes. Formaldehyde has"been polymerized to a synthetic resin which exhibits stability at high +emperatures and has good mechanical properties. The new, presently applied method for the polyme.rizat,ion of formaldehyde is based on the use of monomeric formaldehyde of a high degree of purity (close to 1006) and the application of a special, rigidly controlled process employing catalysts of the ionic type and special methods for the ~cabilization of the polymer. Approved For Release 1999/09/08 :CIA-RDP82-001418000100350001-5 Approved For Release 1999/09/08 :CIA-RDP82-001418000100350001-5 The technological process for the production of po1.~?formal.dehyde is carx?ied out 'as follows . By subjecting a 40yb aqueous solution of ~rntal.deY~yde to the action of alkaline or acidic agents, an intermediate polymer of the ordinary, unstable t~~e, i.e., alpha-polyoxymethylene, is obtain?d. This product is filtered, washed, and dried. The alpha-poiyoxymethylene is heated to produce pure monomeric gaseous formaldehyde . his fbxma'~3.ehyde is additiona?1y dehydrated :Ln special traps, and in the final state of purification, after acquiring a purity of about 1000, is conducted into the polymerization equipment. The polymerization ?makes place in a solvent. Aliphatic amines are most commonly used as polymerizatien cata~.ysts. The polymer that ha.s formed must be stabilized. Tt is treafied wit;h acetic anhydride to stabilize it. Polyformaldehyde is a synthetic resin of the thermoplastic type. Its most valuable property is retention of good operational characteristics at elevated temperatures. Its tensile s?~rength at. room temperature is 700 kgs per cm2. Polyformaldehyde retains a high strength after considerable Elevation of the temperature, i.e., under conditions when the majority of ordinary 1~hermoplastics softsn. 2ts tensile strength at 12Gois X80 kgs per cm~. The moisturF con+en~F of the air has almost no effect on the strength of this polymer. Furthermore, it has a hi~,h limit of fatigue strength, high transverse strength, a low residual deformation, and a low coefficient of moistt~rc absorption. As far as crer,piriU strength (gradual deformation as a .result of prolonged applicat3.on of a load) at low temperatures is concerned, polyformald.i:.hyde is some~ahat inferior. to amorphous polymers (polystyrene and. polymethylmethacrylate), but superior to crystalline polymers, nasrely, polyethylene and polyamides ( i . e . , i'+: has a lower tendency ?t.o creep than the latter). Polyformaldehyde has a. surface which is slippery to t:he touch. Its coefficient of friction (0.1-0.31 is very low in comparison with that of steel ?. The static and r!ynamic coefficients o.f frirtion coincide and do not change with the tempera.tu~re. This makes the material parti cu_larly well suited for the production of ~clf-lubricating bearings and, parts of machines. These characteristics, in combination with +.,he other. mechanical properties of polyforma.ldehyde, make it. possible to produce from this material machine parts which are d3sting~~.ished by a high mechani- cal endurance? These machine parts are suitable for. operation i.n sur- roundings which differ greatly with respect to the temperature and hamidity encountered< They a,re suitable for Llse in a +ropical climate. Because of the high stability of polyformaldehyde to the action of water, it is a good material for water line and water conduit fittings. Polyformaldehyde fittings for this puxpose have, under ordinary conditions, a useful life of 2.0 years. Among the chemical properties of the new polymer, high stability towards the action of air a.t elevated temperatures is worth noting. Exposure +,o elevated temperatures up to 80 for a.n indefi- nite length of time does not result, in impairment of +,he physical proper- ties of the ma.+,eria.l. It can stand. exposure to temperatures up ~-,0 1200 Approved For Release 1999/09/08 :CIA-RDP82-001418000100350001-5 Approved For Release 1999/09/08 :CIA-RDP82-001418000100350001-5 far. shor'`? per.?j,oc',.r~ of time.

Polyamidc.Films "A Remarkable Kind of Film", by A. Papernaya; Moscow, .?rc~lysh].Pnm- Nlsonomicheskaya Gazeta, Vol 1+, No 59 ~ 51~+), 22 May 59, p ?+, calamx 1 Polyamide films were demonstrated by workers a?t the A11-'Union Scientific Research Institute of F~.]m Materials and Artificial Leather. 0. Vorontsova, Senior Scientific Associate at the institute mentioned, demonstrated very thin transparent films which cannot be torn and somewhat 'thicker films which cannot be pierced with a knife or destroyed 'by hammering. The last-mentioned film consists of a technical capron netting made of continuous extruded fibers which have been ceanented by impregnating ?t;he netting with a polyamide copolymer. Avery light,, and. exceed- ingly strong material is produced in this manner. Some reinforced poly- amide films have a tensile strength of 2, 000 kgs per squar. a cent;~meter . Films of this type are impermeable to water and resis~hant to the action. of oil, petroleum, and gasoline. Polyamide films can be modified for many different application by combining them with other polymers. Thus, by combining polyamide.resin with even a small quantity of phenol resin, one may increase its '~~n.sile strength by one third. By adding to polyamides other re~~ins, on.e may produce a material which is stable at temperatures down to minus 50?. A softer and more elastic polyamide resin can be obtained by combining polyamide with different grades of rubber. Films made of resins of this type are resistant to ageing. The technology of their proti:action, is very simple, to V. Alekseyenko, director of the All-onion Scientific Research Institute of Fi]m Materials and Artificial Leather If films of this type which have been rein:['orced with a capron netting are used for the insulation cf concrete tanks for gasoline, the gasoline will not? seep through cracks formed in the concrete. Plastics of this type axe also asi excellent material for the construction of petroleum pipe l.i~.les . I:t, is assumed th;~t films of the type described can be used to replace ?hhe steel parts protecting. guides of machine tools for metal cutting. '?'hes+e films will also be used as wall covers and material for curtains on passenger planes and railroad cars. Another prospective application ir: a,s a material for raincoats and tarpaulins .

The two principal classes of extrac?F,ing ageni;sc, ~.e., arpmzc~?iaspl~orus compounds and amines, are consid.ex?ed., and the influence exerted by different factors on extraction processes is discu~.;5ed,. Examples are given of the application of adsorption an+]. extraction proces:~es at plants converting uranium ores . 17,ze following general concl?usio.r_s are drawn: The present trend is away from the separation of solids from liquid phases and towards the extraction of uranium d.irect;ly from pulps. The RTP process, as applied in the US has not lived up 'to expectations because of the complexity of the equipment needed and t;he ?unsuit:~bility for the treatment of thick pulps of the method. on which tY?e process i? based. Attempts are being made to develop new processes foz? a. ~~,or;p?;;ior.. from pulps, as for instance, adsorption by a pulsating layer of resJ.n. There is a tendency in current worlt to develop technological metYioas of treatment in which leaching is combined with ex?tract;ion, so gnat the amount of acid used is reduced ?to the gx?eatest possible ex?f;ent and 'the degree of extraction of uranium is incrcasc;d. There is, furthermore, a tendency to eliminate filtration after, leaching of the o,re and. ?!;o replace this step with countercurrent decantation in which flocculating agents are used. 1~+.

This property was used to separate uranium from iron, beryllium, and other elements in analytical determinations of uranium. In the work repor'ced at present, an attempt was made to clarify the nature of the interaction between hexavalent uranium and hydroxylamine. It was established that the compound [NH3OH ]2 U0~ ?H20 is formed by uranyl with hydroxylamine in the pH range of 6-8. In the pH range above 8, soluble complex compounds of uranium are formed which have the. constitution ONH3 HONH where Me = an ion of an alkali metal. Some properties of these compounds were investigated, including solubility, density, and electrical conductivity. 18.

Mt~,achev; l~~~scaw, Ato;~u~Nya Ene_ rgiya, Vol 6, No 5, May 59, PP 533-539 It is brought out that as a result of irradiat:ton with neutrons, uranium hexafluoride i.s decomposed with the format:ton of 1c~wer uranium fluorides (i;here is apparently decomposition into UF5 and fluorine). T]Ze rate of decomposition corresponds approximately to G ~~ 0.5 mo':h~100 electron volts or 0.21 mols~hour per one lrw of pcwer generated in the gas. The dissociation of UF6 produced by irradiatian is counterac?tcd by recombination of the dissociation products formed. As a result, a state of equilibrium between free fluorine and tTF~ is establshed. The position of this equilibrium depends on the intensity of irradiatian. In the presence of fluorine, uranium hexafluoride is a compaunl which is ,~tabl.e towards the effects of radiation even at room temperature, ?wheii the velac- ity of recombination is relatively Iota. Uranium hexafluoride can be used ?as a fuel in nuclear reactors. An experimental reaetar emplaying this compound as a fuel has actually been constructed (cf paper No ~?=502 by I. K. Kikoin, V. A.

The relative changes in the electric resistance and heat conductivity were found to be lower in the case of the less graphitized samples. The curves describing the dependence of the heat conductivity on the temperature indicate that radiation defects produced in the crystalline lattice of graphite exert an action on the propagn{`.on of thermal vibrations and act as permanent dispensers of the type of crystal boundaries or impurities. The effect of radiation defects on the electrical conductivity is determined by the appearance of additional traps of carriers of the electrical current.

Organic Moderators "The Application of Organic Compounds As Moderators in Nuclear Reactors," by B. G. Dubovskiy and M. N.

A small increase in the volume of the core takes place as a result of the leakage of neutrons-from the reactor. The age of neutrons in liquid organic compounds increases at a slower rate than the concentration of hydrogen nuclei. Because carbon is present in the organic liquid compounds, the neutron age in these liquids is much lower than in water at the same concentration of hydrogen nuclei. This property of organic liquids, e.g., isoamyl alcohol, suggests that it would be of advantage to use them as biological protective agents to shield nuclear reactors of small dimensions. To obtain more precise results in comparative experi~, ments carried out on reactors employing organic liquids. as moderators, it is advisable to rise as fuel uraniium wi h a 'low degree of enrichment.

On the factors Which Influence the Direction of the Reactions Between Triarylmethyl Halides and Silver Dialkylp osphites "The Action of Triarylmethyl Halides on Silver. Dialkylphosphites;' by A. Ye.

Arbuzov hs~d previously shown that triphenylmethyl chloride and triphenylmethyl bromide react with silver dialkylphosphites in two different directions depending on the nature of the reacting halide. The first type of reaction, that involving triphenylmethyl chloride, can be r.:presented as follows: (RO)~POAg + clc(c6H5~3 -~; AgCl -f- (R~a~~C(C~~5)3, ~l) i. e., mixed esters of phosphorous acid are formed.

The authors were anxious to learn, after studying these reactio:~s, how silver dialkylphosphites would react with other secondary radicals. The following represents the results of the ir~investigation: 1. The direction of the reaction between silver dialkylphosphitas and triarylmethyl halides is influenced by the structure of 'the 7?adicals in the dialkylphosphites, the nature of the halide and the substituent group in the nucleus. 2. The silver salts of diethyl-, diisobutyl-,~diisopropyl~, and di- sec-butylphoaphorous acids and triary7methyl chloride react to yield mixed esters of phosphorous acid (1st type). 3.

S ilver dialkylphosphites containing secondary radicals and tr.iph- enylmethyl bromide yield mixed esters of phosphorous acid (1st type). 5. The presence of a substituent in the aromatic ring of the halide derivative also influences the directiun of the reaction; if the substituent is chlorine, the reaction proceeds according to the first type; if the sub... atituent is a methyl group, the reaction is of the second type. 27.

Weld metal strengths of joir_ts of E2437B in thicknesses up to 100 mm welded with plates of E1437A in a ANF-5 bath equaled g0~ of that of the parent metal. The authors believe that high heat resistance of welded joints of E1437B in thicknesses up to 20 mm may also be obtained by a certain decrease in heating time for quenching and, possibly, in the duration of aging. Preliminary cold work- ing of welded joints before quenching also leads to an increase in heat resistance. 124.

When ferrite content is limited to 596, particles of the 6 'phase are sufficiently stable and ensure the re~ quired properties for operation at 600oC up to 100,000 hours. Increasing ferrite content above 596 results in rapid coarse separation of the 6 -phase and decrease in ductility and impact strength. Austenitization of the deposited metal after welding so that ferrite content is approximately 596 results in the best heat resistance for operation at temperatures lower than 600?C. 1250 New Mills for Rolling Ball Bearings "Mi'l1s for Transverse Helical Rolling of Balls," by 7~e.

Increased~Niobium Conten+ for Hi her Corrosion Resistance "Radio~~aphic Exs.mination of the Distribution of Niobium in Stainless Steel," by L. S.

Baknrakh, All-TJnion Scientific Re- search Snstitute of Hard Alloys; Moscow, S_varochn_oye Proiz- vodstvo, No 1, Jan 59, pp 20..2?_ v Welds of 18-9..type stainless steel sheets with niobium were studied with the aid of the radioactive isotope Nb -95 to determine the effect of heating conditions on the formation and solution of carbides of niobium. Stainless steel welds with an increased content of niobium (ratio of Nb to C equal to 10 to 13) are recommended for intergranular corrosion sta- bility at operating temperatures of 550 to 650?C. Steel welds with a decreased content of niobium (ratio of Nb to C equal to 8) must not be heated in excess of 1,200?C because of the solution of the carbides of. niobium and its negative effect on corrosion stability. A radical method for incre~~sing corrosion stability consisting of heating to 850-900oC and holding for 3 hours results in the formation of carbides of niobium and the simultaneous withdrawal of carbon from the solid solution. Formation of carbides of chromium at operating temperatures is prevented even in steel with decreased contents of niobium by this method. It is noted that although ?the experiments were conducted on stainless steel weld points containing niobium because of difficulty of introducing titanium into a weld point, the results may be related to stainless steel containing titanium. However, me.ximum heating teml.~~:;ratures must be lower for steels containing titanium, as carbides of titanium go into solution at a lower temperature than those of niobium. -9fl- Approved For Release 1999/09/08 :CIA-RDP82-001418000100350001-5 Approved For Release 1999/09/08 :CIA-RDP82-001418000100350001-5 'GT:CT .
