Abstract

FIELD: chemistry.SUBSTANCE: invention relates to a method of producing tetranitrosulphoxy diphenylamine by nitration of phenothiazine with nitric acid, characterised by that, in order to increase purity of end product, process is carried out in two steps: at first step with 53-58 % acid, and at second step with 98 % acid.EFFECT: obtaining tetranitrosulphoxy diphenylamine.1 cl, 1 ex
