Japanese Patent JPS6228783
Kind Code:
B2
Abstract:
Process for the preparation of a chlorothioformate of the formula in which R is alkyl, lower cycloalkylmethyl, lower cycloalkyl-lower alkyl, phenyl, chloro-substituted phenyl, benzyl or chloro-substituted alkyl, the chloro substituent being located no closer to the sulphur atom than on the gamma -carbon atom, with the exception of ethyl chlorothioformate, in a two-step process and in the presence of an active carbon catalyst, by reaction of a mercaptan with phosgene in the liquid phase. Only a minimal amount of disulphide by-product is formed, and the production capacity is increased.
