Abstract
An N-aryl derivative of a hydrocarbon which contains at least three condensed rings or of a carbazole containing the nucleus of such a hydrocarbon, or an oxy derivative of such an N-aryl derivative is treated with sulphur or an agent yielding sulphur whereby sulphurized dyestuffs are obtained. In examples: (1) b -oxyanthracene is condensed with p-aminophenol to give 2 - (4<1> - oxyphenyl)aminoanthracene which is sulphurized by heating with sulphur in cyclohexanol; (2) an indophenol is produced from quinonechlorimide and a -oxyanthracene and after reduction to the leuco compound by means of sodium sulphide is sulphurized with a mixture of sodium tetrasulphide, sulphur, and cyclohexanol; (3) quinonechlorimide is condensed with the carbazole derived from 1-phenylaminoanthracene; after reduction, the resulting leuco compound is sulphurized. Examples of dyeing p cotton with the product of example 1 in the usual sodium sulphide bath and with the product of example 3 in a hydrosulphite vat are given. N-aryl derivatives of phenanthrene, acenaphthene, chrysene, pyrene and picene may be subjected to sulphurization, which may be effected in the presence of iodine, benzidine, urea, cyanamide, diphenylurea, dicyandiamide or guanidine.
