Abstract
Dyes are made by acylating one molecular proportion of a 4.8-diamino-1-aroylaminoanthraquinone with at least two molecular proportions of an acylating derivative of an anthraquinone-2-carboxylic acid which carries in the 1-position an amino group, a nitro group or a halogen atom, so that two acyl radicals are introduced. The nitro group or halogen atom may be subsequently converted to amino. Examples describe the reaction of 1-nitro-anthraquinone-2-carboxylic chloride with 4.8-diamino-1-benzoylamino- and 1-p-methoxybenzoylamino-anthraquinone. 4.8-Diamino-1-p-chlorbenzoylamino and the 1-p-toluylaminoanthraquinone are referred to as starting materials. The 4.8-diamino-1-aroylamino-anthraquinones employed are prepared by reduction of the corresponding 4.8-dinitro bodies with sodium sulphide. Specifications 219,830 and 230,116, [both in Class 2 (iii)], are referred to.
