M echanical Engineering ollege, W uhan Institute of Technology, Wuhan 430074 , hina ; 2. hem ical and Pharm aceutical ollege, Wuhan Institute ofTechnology, Wuhan 430074 , hina) Abstract Themethod of converting thewaste residue of 1- am ino anthraquinone production into valuable dispersible reddish brown E- 3R is introduced in this paper. Them ain constituents of this waste residue are not only the unreacted anthraquinone and 1- nitro anthraquinone, but also byproduct of 1, 5 ( or 1, 8) - dinitroanthraquinone. The anthraquinone and 1- nitro anthraquinone in thewaste residue were first converted into 1, 5( or 1, 8) - dinitroanthraquinone by nitration, and then the ( 1, 5 or 1, 8) - dinitroan- thraquinonewas reduced into the corresponding 1, 5( or 1, 8) - diam inoanthraquinones, and then the chlorinated dyewas obtained by chlorination. One kind of dispersing dyes, dispersing reddish brown E- 3R can be produced by adding dispersant into the original dye and then process
