Abstract
22,824. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. Oct. 20. Dyes, artificial.-A blue-black sulphuretted dyestuff, differing from that described in the French Specification No. 315,669, is produced by oxidizing a mixture of p-amido-p-oxydiphenylamine and phenol with a ferricyanide, hypochlorite, &c., and heating the oxidation product with sulphur, sodium sulphide, and water, and a little common salt, or with an alkali polysulphide. The mass may be used directly for dyeing, or the dye-stuff may be separated by air or acids. The product becomes more greenish-blue-black if the operation is conducted at a higher temperature. The Specification refers also to the French Specifications Nos. 284,387 and 304,884, and to the German Specification No. 116,337.
