Abstract

21,133. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Sept. 18. Samples furnished. Anthracene, dyes derived from.-Vat dyes are obtained by condensing 1-aminoanthraquinone, or derivatives thereof, with halogenfluorenone carboxylic acids; the carboxylic group splits off during the condensation; the products are identical with those described in Specification 7632/10. According to examples, 1-aminoanthraquinone is condensed with dichlorfluorenone- 4-carboxylic acid, 2: 7-dibromfluorenone-4-carboxylic acid, and bromfluorenone carboxylic acid. Dichlorfluorenone-4-carboxylic acid is obtained by treating fluorenone-4-carboxylic acid with fuming sulphuric acid, and treating the resulting disulphonic acid with sodium chlorate and hydrochloric acid. 2:7-Dibromfluorenone-4-carboxylic acid is obtain by treating diazotized bromanthranilic acid with an ammoniacal solution of cuprous ammonium sulphite, and heating the resulting 4:4<1>- dibromdiphenyl-2 : 2<1>-dicarboxylic acid with concentrated sulphuric acid. Monobromfluorenone carboxylic acid is obtained by heating 4-bromdiphenyl-2: 2<1>-dicarboxylic acid with concentrated sulphuric acid.
