If you treat aminoanthraquinones or their derivatives, expediently in a solvent or suspending agent in the presence of or Absence of catalytically active substances such as copper, copper salts, and with or without j Use of hydrochloric acid binding agents, with trichloromethyl sulfur chloride (perchloromethyl mercaptan; Ber. 20, 2377), this leads to new derivatives which can either be used directly as dyes or as starting materials can be used to represent dyes.

Example.

10 parts of 2-aminoanthraquinone, 50 to 100 Parts of nitrobenzene and 4 parts of trichloromethylsulfur chloride are taken for a few hours or Heated to boiling on the reflux condenser until the formation of dye increases no longer occurs. The condensation product is then (expediently without prior Cooling). It can be obtained in its very pure form by recrystallization from quinoline and is then added the elemental analysis values based on the formula

let it close. It ... dissolves in sulfuric acid from 66 ° Be. with brown-red color, in alcohol, benzene, glacial acetic acid, nitrobenzene it is poorly soluble. Cotton is made from the vat obtained with alkaline hydrosulfite solution Colored in brownish-red tones, which when washed and hanging in the air in orange pass over.

Instead of the 2-aminoanthraquinone, its derivatives and other amino or diaminoanthraquinones or their derivatives are used. So you get z. B. off 2 · 6 - diaminoanthraquinone one yellow, from 2-amino-6-oxyanthraquinone one brown 2-Amino-3-methylanthraquinone one orange and one from 2-amino-3-chloroanthraquinone yellow olive coloring vat dye.
