Abstract
Improvements introduced in the object of the main patent, which consist of combining the alkaline hydrolysis of the sulphazine acyl derivative (resulting from the condensation, according to the procedure of the main patent, of the azine amine with a pacilamino benzene sulfonic acid chloride) with a purification of the sulfazine by crystallization of the alkali salt thereof in a relatively concentrated aqueous solution of an alkali hydroxide; refinement that is normally carried out by boiling at reflux, for 15 minutes to 1 hour, of the sulphamine acyl derivative with aqueous sodium hydroxide solution of concentration close to 20%, cooling at low temperature to achieve the crystallization of sodium sulfazine, draining it and washing with very cold solution of 20% sodium hydroxide, redissolving in water sulfazine sodium, and precipitation of sulfazine by an acid.
