Abstract

1,141,245. Anthraquinone dyes. TOMS RIVER CHEMICAL CORP. 28 April, 1967 [28 April, 1966], No. 19752/67. Heading C4P. The invention comprises 1-amino-2,4-dialkoxyanthraquinones. The compounds are prepared by treating 1-amino-2,4-dihaloanthraquinones with an alkanol in the presence of an alkali. The compounds may be hydrolysed, e.g. in acid solution to 1-amino-2-alkoxy-4- hydroxy anthraquinones.
