Abstract
Process for the preparation of vinyloxyane-sulphonic derivatives, of the general formula: CH2 = CH-O-Ar- (SO3R) n wherein Ar denotes an aromatic radical, R a hydrogen atom, a metal or an organic radical and n one of the values 1, 2 or 3, characterized in that it consists of the sulfonation of the β -halogenoethoxy arenes, by the action of a hot sulfonating agent. The beta-β-halogenoethoxyane-sulfonic acids obtained are subjected to the action of an aqueous solution of an alkali hydroxide, losing a halogenated acid molecule and transforming into the alkali salts of the vinyloxyazenesulfonic acids, from which the acids or esters can be prepared. corresponding.
