Abstract

1062. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. Jan. 19. Oxyanthraquinones and their sulphonic acids.- Consists in using mixtures of caustic alkalies and alkaline-earth salts, instead of alkaline earths or mixtures of alkaline earths and alkalies, in the process for producing oxyanthraquinones and their sulphonic acids from anthraquinone sulphonic acids described in Specification No. 25,541, A.D. 1903. In examples, the preparation of erythrooxyanthraquinone, chrysazin, anthrarufin, alpha1, alpha3- and alpha1, alpha4- oxyanthraquinone sulphonic acids from the corresponding disulphonic acids is described. The oxysulphonic acids can be made the principal products by varying the conditions.
