Abstract

288,957. Carpmael, K., and Carpmael, K. S., (Representatives of Carpmael, W.), (I. G. Farbenindustrie Akt.-Ges.). Dec. 10, 1926. Divided on 288,666. Bromo derivatives of 1: 1<1>-dinaphthyl-8 : 8<1>-dicarboxylic acid. - 1 : 1<1>-Dinaphthyl-8 : 8<1>-dicarboxylic acid is converted into a monobromo derivative by brominating it in glacial acetic acid. A dibromo derivative is obtained by treating the acid with excess of bromine in the cold. The products may be converted into the corresponding bromobenzobenzanthrone carboxylic acids by the process described in Specification 288,666.
