Abstract
The invention relates to fine organic synthesis, in particular, to a method for tetrakisazodyes preparation, and can be used in chemical industry. A method is performed by combination of preliminary dianitrated 4,4'-diaminodiphenylamino-2- sulfonic acid with two moles of 2-amino-8-oxynaphthalene-6- sulfonic acid followed by the dinitration of resulted diazocompound, combination with a mixture of 1,3-diaminobenzebe with its N-carboxymethylsubstitued, and isolation of end product.
