Abstract
1,260,755. Production of aromatic carboxylic acids. LUMMUS CO. 28 Feb., 1969 [18 March, 1968], No. 10792/69. Heading C2C. A process for the production of an aromatic carboxylic.acid by the hydrolysis of an aromatic nitrile comprises (a) maintaining an aqueous slurry of the nitrile in contact with a catalyst which is an alkali metal or alkaline earth metal hydroxide, carbonate or salt of an aromatic carboxylic acid or ammonium salt of an aromatic carboxylic acid at a temperature in the range 300-600‹ F. for a period sufficient to hydrolyse a substantial portion of the nitrile, (b) stripping ammonia from the hydrolysate, by countercurrently contacting the hydrolysate with steam and (c) cooling the stripped hydrolysate to a temperature at which the aromatic carboxylic acid separates out. In the examples terephthalic acid is prepared from terephthalonitrile.
