Abstract

1,173,890. Isocyanates. GOSUDARSTVENNY NAUCHNO - ISSLEDOVATELSKY I PROEKTNY INSTITUT AZOTNOY PROMYSHLENNOSTI I PRODUKTOV ORGANICHESKOGO SINTEZA. 8 March, 1968, No. 11391/68. Heading C2C. Isocyanates, including the novel compounds cyclo - hexane - 1,3 - diisocyanate (cis); cyclohexane - 1,4 - diisocyanate (trans); α,#-diphenylethane - 4,4<SP>1 </SP>- diisocyanate; 2,2<SP>1</SP> - dichlorodiphenyl methane - 4,4<SP>1 </SP>- diisocyanate; 3,5,3<SP>1</SP>,5<SP>1</SP> - tetramethyldiphenyl - 4,41 - diisocyanate are prepared from an amine and phosgene, in which process the amine, preheated to a temperature below its decomposition temperature, is caused to react with phosgene, preheated to a temperature above its critical temperature, the temperature of the reaction system being maintained at or above the temperature at which commences dissociation of the hydrochloride of said amine and the pressure being maintained at or above the pressure required to keep all of the components of the reaction system in the liquid phase. The preparation of both the novel and the known isocyanates, hexamethylene diisocyanate; decamethylene diisocyanate; toluene diisocyanate; phenylisocyanate; diphenylmethane-4,41-diisocyanate; dicyclohexyl methane-4,4<SP>1</SP>-diisocyanate; triphenylmethane - 4,4<SP>1</SP>,4<SP>11</SP> - triisocyanate; 3,4 - dichlorophenylisocyanate and 3,3<SP>1</SP>-dimethoxydiphenyl - 4,4<SP>1</SP> - diisocyanate is exemplified.
