Abstract
Process for obtaining sulfonated azonitriles, of general formula ** (See formula) ** wherein R represents a hydrocarbon radical, optionally substituted by an alkoxycarbonyl group R 'a hydrocarbon radical, and X a hydrogen atom or an alkali metal, characterized in that they are prepared by simultaneous action of hydrazine and hydrocyanic acid on a ketone- sulfonate. The hydrazo derivative obtained is then oxidized to transform it into an azo derivative. (Machine-translation by Google Translate, not legally binding)
