Abstract

Condensation products of the benzanthrone series are obtained by condensing benzanthrone-peri-dicarboxylic acid, anhydride, or a derivative thereof, including ring substitution products, with an aromatic o-diamine at a temperature below 80 DEG C. in an indifferent solvent. The products, which are dicarboxylic imides are further ring-closed to give the products of parent Specification, by heating to a higher temperature. According to examples, benzanthrone-peri-dicarboxylic anhydride is condensed with o-phenylenediamine, followed by ring-closure, with 2 : 3-diaminotoluene, followed by ring-closure, with p-chloro-o-phenylenediamine, followed by ring-closure, with 2-chloro-4 : 5-diaminotoluene, followed by ring-closure, with p-ethoxy-o-phenylenediamine, followed by ring-closure, with 1 : 2-diaminonaphthalene, followed by ring - closure, with 4 : 5 - diaminoacenaphthene, followed by ring-closure, with o-o<1>-diaminobenzidine followed by ring-closure to the dye ; 7-methyl-benzanthrone-peri-dicarboxylic anhydride is condensed with p-ethoxy-o-phenylenediamine; 5 : 6-benz - benzanthrone - peri - dicarboxylic anhydride, 7 : 8-benz - benzanthrone - peri - dicarboxylic anhydride, and chlorobenzanthrone-peri-dicarboxylic anhydride are condensed with o-phenylenediamine, followed in all cases by ring-closure. Benzanthrone derivatives.--7 - methyl - benzanthrone-peri-dicarboxylic anhydride is obtained by melting 4-p-toluyl-1 : 8-naphthalic acid with aluminium chloride; 5 : 6-benz- and 7 : 8-benz-benzanthrone-peri-dicarboxylic anhydrides are obtained by melting 4-a -naphthoylnaphthalic anhydride, obtainable by oxidizing 5 - b - naphthoylace-naphthene, and 4-b -naphthoylnaphthalic acid, obtainable by oxidizing 5-b -naphthoylacenaphthene, respectively, with aluminium chloride; chlorobenzanthrone-peri-dicarboxylic anhydride is obtained by condensing 4-benzoylnaphthalic acid anhydride.
