摘要： In the enzyme-mediated synthesis of an ester or lactone from at least one carboxylic acid of the formulaR--CH.sub.2 --CH.sub.2 --COOHwhereinR is a hydrogen atom, or a hydrocarbon radical which has 1 to 21 carbon atoms and which can be optionally substituted by hydroxyl groups or alkoxy groups with 1 to 10 carbon atoms,with at least one primary or secondary alcohol having 1 to 15 carbon atoms, the improvement which comprises employing as the enzyme the esterase from Mucor miehei and effecting the synthesis in the absence of water. Advantageously, the synthesis is effected at about room temperature, the mol ratio of carboxylic acid to alcohol is from about 1:1 to 1:1.1, and the enzyme is used in a quantity of about 3 to 20% by weight of the carboxylic acid. The absence of water facilitates recovery, as by distillation.
