Abstract
Process for the manufacture of new diisothiocyanates, of the general formula ** (See formula) ** in which: - R represents a hydrogen atom or an alkyl or alkyloxy radical containing from 1 to 4 carbon atoms; A and A ', identical or different, each represent a simple union or a straight or branched alcohol radical containing from 1 to 6 carbon atoms and are located in meta or for one in relation to the other, characterized in that it condenses the thiophosgene (CSCl2) in a diamine of the general formula: ** (See formula) ** in the presence of an excess of thiophosgene and an acid acceptor.
