Abstract: IN WHICH ONE X is chloro and the other X is hydrogen or each X is chloro; and WITH AIR OR OXYGEN OR WITH 10 TO 30% BY WEIGHT NITRIC ACID TO FORM THE CORRESPONDING CARBOXYLIC ACID FOLLOWED BY CYCLIZATION OF THE LATTER. 1-CHLOROANTHRAQUINONE-2,3-DICARBOXYLIC ANHYDRIDE OR 1,4-DICHLOROANTHRAQUINONE-2,3-DICARBOXYLIC ANHYDRIDE IS OBTAINED IN A GOOD YIELD. Each is a valuable dye intermediate.

A process for the production of an anthraquinone-2,3dicarboxylic anhydride bearing chlorine as a substituent in the 1-position or in the 1- and 4-positions by oxidation of a trimethyl compound of the formula:

Abstract: The production of 3,6-dihalodiphenylalkanes by reaction of a diphenylalkane with a halogen and the novel 3,6dihalodiphenylalkanes themselves. The new compounds which can be prepared according to the process of the invention may be used as dispersing agents in dye/styrene mixtures and also as dyeing auxiliaries. They are also valuable starting materials for the production of dyes and pesticides.
