1366645 Dithiocarbamic acid salts UNIROYAL Inc 7 Sept 1971 [9 Sept 1970] 41672/71 Heading C2C [Also in Divisions B5 and C3] Zinc n - dodecylisopropyldithiocarbamate, which is used as a vulcanizing accelerator in rubber compositions, is prepared by reacting ndodecylisopropylamine with carbon disulphide and zinc sulphate. The zinc salts of n-decylisopropyl, n-octylisopropyl, n-octyl-(1,3-dimethylbutyl), n - dodecyl - (1,3 - dimethylbutyl), ndodecylcyclohexyl, n - octadecylisopropyl, noctadecyl - (1,3 - dimethylbutyl) and n - (mixed C 16-18 alkyl) isopropyl dithiocarbamates are prepared analogously.
