Synthesis of Vat Blue Anthraquinone (Indantrone) Dye With Improved Surfactan

Abstract

The results of the study of the process of synthesis of vat dye from chemical components isolated from coke oven gas and resin after coking coal are shown. The schemes of reactions of obtaining intermediates for the synthesis of the dye are given. block diagrams of chemistry of technological operations are made, physicochemical color properties of this dye are studied.
