Abstract

12,921. Ransford, R. B., [Cassella & Co., L.]. May 27. [Cognate Application, 22,306/10.] Anthracene, dyes derived from.-Vat dyes are obtained by heating di- and tri-anthraquinonylimides with anhydrous aluminium chloride. According to examples the following parent materials are treated :-a-anthraquinonyl- 1-aminoanthraquinone, alpha-alpha-dianthraquinonyl- 1:5- or -1 :8- diaminoanthraquinone, #-anthraquinonyl- 1-aminoanthraquinone, #-#-dianthraquinonyl- 1 :5- diaminoanthraquinone. Diluents such as nitrobenzene may be employed in the process and the shades produced may be varied by altering the proportions of aluminium chloride, the temperature, or the duration of treatment. Specifications 25,551/08 and 15,846/09 are referred to.
