    Abstract: AN IMPROVED PROCESS FOR THE PRODUCTION OF 1,2-DIAMINES BY REACTION OF 1,2-EPOXIDES WITH AMMONIA, PRIMARY AMINES OR SECONDARY AMINES IN THE PRESENCE OF WATER, HYDROGEN AND HYDROGENATION CATALYSTS AT ELEVATED TEMPERATURE AND SUPERATMOSPHERIC PRESSURE WHEREIN THE IMPROVEMENT COMPRISES USING A SUPPORTED HYDROGENATION CATALYST HAVING A LARGE INTERNAL SURFACE AREA. THE PRODUCTS ARE SUITABLE AS COMPLEX-FORMING SUBSTANCES FOR HEAVY METAL IONS.

    CPC classification number: C07C209/72

    Abstract: A PROCESS FOR THE CONTINUOUS PRODUCTION OF DIAMINODICYCLOHEXYLALKANES BY CONTACTING DIAMINODIPHENYLALKANES WITH HYDROGEN AT ELEVATED TEMPERATURE AND SUPERATMOS-PHERIC PRESS PHERIC PRESSURE IN THE PRESENCE OF HYDROGENATION CATALYSTS CONTAINING COBALT, WHEREIN THE IMPROVEMENT CONSISTS IN CARRYING OUT THE REACTION AT A TEMPERATURE OF MORE THAN 180*C. AND A PRESSURE OF MORE THAN 50 ATMOSPHERES IN THE PRESENCE OF A HYDROGENATION CATALYST CONTAINING COBALT WHOSE COPPER CONTENT IS LESS THAN 0.5% BY WEIGHT WITH REFERENCE TO COBALT AND MAINTAINING A WATER CONTENT OF LESS THAN 0.4% BY WEIGHT IN THE REACTION MIXTURE. DIAMINODICYCLOHEXYLALKANES ARE SUITABLE AS HARDENERS FOR EPOXY RESINS AND FOR THE PRODUCTION OF POLYAMIDES.

    Abstract: Styrene is polymerixzed with optionally up to 45% by w. of acrylonitrile a - or nuclear-methyl styrene, and mono- or di-chlorostyrene, at 80-180 DEG C., the polymerization being carried on until the coversion if 45-95% and the remaining monomers and any diluent being removed by degassing in vacuo, and prior to degassing there is added to the polymerization mixture, before or during polymerization, 0.1-5% of an ester of a dimer or trimer of a fatty acid which is oleic, linoleic, linolenic or elaidic acid, with a C1- 18 alcohol and/or an ester of a C18 acid with an alconol which has been obtained by hydrogenation of the above dimer or trimer and/or an alcohol which h as been obtained by hydrogenation of the above dimer or trimer. the polymerization may be carried out in the presence of up to 50% of diluent e.g. ethylbenzene. The ester may be te butyl or ethylhexyl ester of the fatty acid. The polymerization may be continuous. The styrene may be polymerized in the presence of a rubber comprising 25% styrene and 75% butadiene.
