    摘要: A process for preparing high molecular weight acyclic polyamines comprising providing a reaction mixture that includes at least a first component comprising a first organic, nitrogen-containing compound that contains at least two non-tertiary amine groups separated from one another by a ternary or higher carbon atom spacing that can be transaminated in the presence of a hydrogenation/dehydrogenation catalyst to form a mixture of higher molecular weight, acyclic polyamines while minimizing the formation of cyclic polyamines.

    摘要: A process for the continuous preparation of 3,3'-dichlorobenzidine dihydrochloride from 2,2'-dichlorohydrazobenzene by treatment with aqueous sulfuric acid, which comprises treating the 2,2'-dichlorohydrazobenzene, dissolved in a water-immiscible aromatic solvent, continuously at temperatures of from about 20.degree. to about 50.degree. C. in the presence of an alkali metal salt of an alkyl (C.sub.8 -C.sub.23)polyglycol ether sulfate, with such an amount of from about 50 to about 80 % strength aqueous sulfuric acid that the suspension formed remains conveyable, subsequently diluting the suspension emerging from the reaction zone with water, again continuously, and subsequently heating the suspension to a temperature of from about 90.degree. to about 95.degree. C. until a solution is obtained, separating off the aromatic solvent from the hot, sulfuric acid aqueous phase, and precipitating the 3,3'-dichlorobenzidine dihydrochloride by adding hydrochloric acid to the sulfuric acid solution which remains and filtering off this product.

    摘要: A process is described for the preparation of polymethylene polyphenyl polyamines containing from 40 to 60 percent by weight of diamine and also containing markedly less high molecular weight polyamines than products hitherto available. Phosgenation of the polyamines gives the corresponding mixture of polymethylene polyphenyl polyisocyanates of markedly lower viscosity and lighter color than products hitherto available, and yielding polymer foams which are substantially white in color.The process comprises condensing aniline and formaldehyde (molar ratio 4-10:1) in the absence of catalyst, separating water from the resulting aminal mixture, contacting the aminals at 20.degree. C to 60.degree. C with a solid catalyst (diatomaceous earths, clays, zeolites) until formation of benzylamines is substantially complete, distilling aniline from the resulting benzylamines under reduced pressure and below 150.degree. C until the aniline content is 3 to 22 percent by weight, and contacting the resulting product with a solid catalyst (diatomaceous earths, clays, zeolites) at 100.degree. C to 190.degree. C until conversion to polymethylene polyphenyl polyamines is complete.

    摘要: 1-Azacyclopentano(1,2-a)adamantane compounds and derivatives thereof which have antiviral and anti-inflammatory properties and which are useful cardiovascular agents may be prepared starting from 2-adamantanones or substituted 2-adamantanones and proceeding through a series of intermediate compounds to the corresponding 1-azacyclopentano(1,2-a)-adamantanes. Derivatives may be obtained by reacting the latter with an alkyl or alkenyl halide, haloalkylamine or a haloalkyl substituted amine, a haloalkylcarboxylic acid, an aralkyl halide of up to 10 carbon atoms, or a haloalkyladamantylamine or haloalkyl substituted adamantylamine. The 2-adamantane alkylamine intermediates for the 1-azacyclopentano-(1,2-a)adamantane compounds also have antiviral and anti-inflammatory properties and are useful cardiovascular agents.
