Abstract

274,894. I. G. Farbenindustrie Akt.- Ges. July 24, 1926, [Convention date]. Acenaphthene carboxylic acids: chloroform. - Acenaphthene carboxylic acids are obtained by treating acetyl-, diacetyl-, chloracetyl-, or di(chloracetyl)-acenaphthene or a substitution product of any of them with an alkaline hypochlorite solution, chloroform being eliminated. In an example, 5-chloracetylacenaphthene or 5- acetylacenaphthene is heated with an excess of alkaline hypochlorite solution, and, on cooling, the sodium salt of 5-acenaphthenecarboxylic acid separates. An acenaphthenedicarboxylic acid is obtained from the di(chloracetyl)acenaphthene produced from acenaphthene and 2 molecular proportions of chloracetylchloride, or by condensation of 5-chloracetylacenaphthene with chloracetylchloride. In the same way, 5-bromo-6- acenaphthenecarboxylic acid may be prepared from 5-bromo-6-acetylacenaphthene, obtained by bromination of acetylacenaphthene in presence of chloroform.
