| abstract | 270,778. British Dyestuffs Corporation, Ltd., Shepherdson, A., Tatum, W. W., and Bunbury, H. M. Jan. 11, 1926. Acidyl-1: 4-diaminoanthraquinones are obtained by treating leuco-1: 4-diaminoanthraquinone with acylating agents in presence of nitrobenzene or nitrotoluene; the leuco compound is simultaneously acylated and oxidized. The leuco-1 : 4-diaminoanthraquinone can be obtained by the method described in Specification 268,891. According to examples the leuco compound is converted into 1 : 4-dibenzoyldiaminoanthraquinone, 1-amino-4-benzoylaminoanthraquinone, and anthraquinone-1 : 4-dioxamic acid by treatment in nitrobenzene with benzoyl chloride, benzoic anhydride, and anhydrous oxalic acid respectively. Specification 255,630 also is referred to. |
