Abstract
A liquid-phase process for hydrolyzing a carboxylic acid alkyl ester having 2 to 18 carbon atoms to provide a product mixture comprising a carboxylic acid and an alcohol comprising contacting a feedstock comprising the carboxylic acid alkyl ester and water with an acidic carbon catalyst under reaction conditions sufficient to form the product mixture comprising the carboxylic acid and the alcohol. Suitable acidic carbon catalysts include charcoal and carbons produced from a variety of sources including coconut shells, coal, wood and peat. Carbon catalysts may be rendered acidic by treatment with nitric acid.
