Abstract

Tetraaminobenzoquinone is made by treating a 2,5 di-(C2- 6-acylamino)-3,6-diaminobenzoquinone or its salt with concentrated H2SO4 and converting the sulphate obtained to the desired product with alkali; alternatively, the corresponding hydroquinone may be used, when air is introduced at the final stage.
