Abstract

299,972. Carpmael, A., (I. G. Farbenindustrie -Akt.-Ges.). Sept. 30, 1927. Anthraquinone vat dyes are obtained by alkaline condensation of the a : #-di-9-anthronyleneethylenes obtainable by condensation of two molecular parts of an anthrone with one molecular part of glyoxal according to Specification 299,817. In examples, the condensation product from anthrone and glyoxal is fused with alcoholic potash to give a claret red dye, while by employing, instead of anthrone, 2-phenylanthrone, a violet dye, and with 1-or 2-chloranthrones, claret red dyes are produced. The substituted anthrones employed are prepared by reduction of the corresponding anthraquiuone derivatives.
