Synthesis method

Brief description of the production method

1,4-dihydroxyanthraquinone is obtained by condensation of hydroquinone and phthalic anhydride, and then ammoniated to obtain 1,4-diaminoanthraquinone leuco body, which is then oxidized with fuming sulfuric acid. Raw material consumption quota: phthalic anhydride 2131kg/t, hydroquinone 887kg/t, ammonia (20%) 10788kg/t, oleum 3580kg/t.

Purpose

Mainly used to prepare anthraquinone series vat dyes, disperse dyes, acid dyes, etc., such as vat olive R, vat brown BR, disperse violet H-FRL, disperse emerald blue H-GL and other dyes. It can be used by itself as a disperse violet dye.
