For the preparation of saline derivatives of mercaptoethansulfonic acid belonging to the class of the salts of alkali metals and of the salts with basic aminoacids, the sodium salt of the acid is obtained with a process comprising the reaction between sodium bromoethansulfonate with thiobenzoic acid and sodium bicarbonate and subsequent reaction of the resulting sodium benzoylethansulfonate with ammonia in water solution.
