Abstract

324,311. Dunworth, J. F., Thomas, J., and Scottish Dyes, Ltd. July 16, 1928. Benzoylaminoanthraquinones are made by treating aminoanthraquinones, containing only one anthraquinone nucleus, at about 100‹ C. with not less than 3 molecules of benzoylating agent for each amino group to be benzoylated. The benzoyl product is separated by filtration and the excess of benzoylating agent re-used. Benzoyl chloride and o-, m- and p-chlorbenzoylchlorides are specified as benzoylating agents. In examples, (1) 1-benzoylaminoanthraquinone is made by treating 1-aminoanthraquinone with benzoylchloride (5 mols.) at 100‹ C. in chlorbenzene or nitrobenzene solution. (2) To the filtrates from (1) more benzoylchloride is added and the mixture used for benzoylating 1-aminoanthraquinone. (3) 1-amino-5-chloranthraquinone is treated as in (1) and (2). (4) 1-amino-5-chloranthraquinone is benzoylated at 96-98‹ C. with excess benzoylchloride in presence of sodium acetate and nitrobenzene and the product filtered. The filtrates are re-used. (5) Dibenzyl-1: 5-diamimoanthraquinone is prepared from 1 : 5-diaminoanthraquinone and excess of the benzoylchloride at 96‹- 98‹ C. The Provisional Specification refers also to acylation of aminoanthraquinones in general and includes the following examples (1) 4 : 4'-diamino- 1 :1<1>-dianthrimide is benzoylated in chlorbenzene with an excess of benzoychloride in the water-bath, (2) leuco-1 : 4-diaminoanthraquinone is benzoylated in nitrabenzene at 95‹-100‹ C. with excess of benzoylchloride ; benzoyl-1 : 4- diaminoanthraquinone is obtained on filtration, (3) benzoylchloride is added to the filtrates from (2) and the mixture used for benzoylating more leuco-1 : 4-diaminoanthraquinone.
