Abstract

300,683. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Aug. 17, 1927. Pyridazinanthrone derivatives of 1 : 2; 5 : 6- diphthaloyl acridone containing an aroylamino group, which are green vat dyestuffs, are prepared by the action of hydrazine on an aroylamino-1 : 2: 5: 6-diphthaloylacridone. or by the action of hydrazine on an amino-1 : 2; 5 : 6-diphthaloylacridone with subsequent aroylation of the product. In examples, mono -benzoylamino - 1 : 2; 5 :6-diphthaloylacridone described in Specification 295,645, and the corresponding o-chlorbenzoyl and m-methoxybenzoyl derivatives, and also the amino-compound itself, are condensed with hydrazine, the product from the amino-compound being subsequently benzoylated. Specification 25677/11 also is referred to. Aroylamino-1 : 2 5 : 6-diphthaloylacridones. - The o-chlorbenzoyl and m-methoxybenzoyl derivatives are prepared by aroylation of the aminoderivative as described in Specification 295,645.
