Abstract

4.5-, 4.6- and 4.7-Dichloro-1-benzoylaminoanthraquinones, which may be substituted in the benzoyl radical, are made by chlorinating the corresponding 5-, 6-, and 7-chloro-1-benzoylaminoanthraquinones in nitrobenzene or other high-boiling inert solvent in the presence of acetic acid and an acid-binding agent, such as sodium or potassium acetate, or by benzoylating 1-amino-5-, 6-, 7-chloroanthraquinones in nitrobenzene or other high-boiling inert solvent, and then, without isolation of the benzoylamino compound, chlorinating as above. The products are dyestuff intermediates, which yield anthrimides with aminoanthraquinones. In examples, 1-amino-5 (or 6- or 7-)-chloroanthraquinone is benzoylated and chlorinated in nitrobenzene, using acetic acid and sodium acetate during the chlorination. Other solvents specified are trichloro-ethylene, and mono-, di-, and tri-chlorobenzenes. Substituted benzoyl chlorides, such as methyl, chloro, or nitro benzoyl chlorides may be used. Specification 414,529 is referred to.
