Abstract

Monobasic carboxylic acid anhydrides are prepared by the reaction of equimolar quantities of an acyl halide, ROhal, and an alkali metal salt or ammonium salt of a monobasic acid, R1COOH, wherein R and R1 may be the same or different and represent either a substituted or unsubstituted aryl radical or an alkyl radical containing at least 11 carbon atoms, in an aqueous medium in the presence of a tertiary base as catalyst and at ambient temperatures and pressures and separating the resulting solid anhydride from the liquid reaction mixture. Suitable starting materials are the acyl derivatives and salts of benzoic acid which may be substituted in the nucleus by, e.g., nitro-groups, halogen atoms or C1-C5 alkyl groups. Suitable aliphatic reactants are the appropriate derivatives of lauric and palmitic acids. The catalyst may be a trialkylamine, e.g. triethylamine, or a pyridine, e.g. 3-aminopyridine, picolines, lutidines or colidines. Examples describe the preparation of (1), (4), (5) and (5A) benzoic anhydride, (2) toluic anhydride, (3) 3: 5-dinitrobenzoic anhydride, (6) o - chlorobenzoic anhydride, (7) lauroyl anhydride and (8) palmitic anhydride.
