The esterification of oleic acid with alkyl alcohols in solv ent-free systems was catalyzed by an immobilized lipase from Candida sp . 99-125. The influence of several factors, including enzyme concentration, temperature, molar ratio between oleic acid and alkyl alcohols, and structure of alcohol was also investigated. The results indicated that the reactions catalyzed by lipase at 20 o C, in the presence of 3% (w/w) lipase, on the molar ratio of 1:1 between oleic acid and alcohols, afforded products in high yield. It showed high selectivity to primary and low selectivity to secondary alcohols and tertiary alcohols because of the sterically hindered effect. Methanol has certain toxicity on the activity of the lipase. The lipase from Candida sp. 99-125 was identified to be an effective catalyst in the esterification of alcohol and oleic acid at low temperature.
