摘要： 1,235,778. N,N-Biscyanoethylated amines. TOYO BOSEKI K.K. 15 Aug., 1969 [19 Aug., 1968], No. 40826/69. Heading C2C. N,N-Biscyanoethylated amines of the general formula (wherein R 1 and R 11 are each lower alkyl groups having from 1 to 8 carbon atoms, or together represent an alkylene group having from 4 or 5 carbon atoms), and also mixtures of these amines with acrylonitrile, may be prepared by reacting an amine of the formula or its N-mono-cyanethylated derivative, with acrylonitrile in the presence of an acidic catalyst. Suitable catalysts are protonic acids, Lewis acids, e.g. metal halides, and amine and ammonium salts, e.g. with nitric or hydrochloric acids, and between 1 and 100 mol. per cent (based on the amine) is normally employed. The resultant bis-cyanoethyl compounds can be reduced by conventional methods to yield the corresponding bis-3-aminopropyl derivatives. Specified biscyanoethyl compounds include N,N - bis - (2 - cyanoethyl) - 2 - aminopropane, - 2-aminobutane, and -cyclohexylamine.
