Abstract

2105. Newton, P. A., [Farbenfabriken vorm. F. Bayer & Co.]. Jan. 27. [Addition to 7819/09.] Indigoid dyes.-Vat dyes are obtained by condensirg dihalogenindoxyls or their acetyl derivatives with acenaphthenequinone or its halogen derivatives. According to one example, a product identical with that described in Specification 27,773/09 is obtained by condensing 5 : 7-dibromdiacetylindoxyl withacenaphthenequinone. The 5:7-dibromdiacetylindoxyl is obtained by treating 4 : 6-dibromphenylglycine-2-carboxylic acid with acetic anhydride and sodium acetate, according to the process described in Specification 6211/98. 5 : 7 dichlorindoxyl is also specified as a component. The Provisional Specification also refers to the use of chlor- or bromindoxyls.
