摘要：

Phenolic acid esters were synthesized by direct esterification catalysed by an immobilized lipase obtained from Candida antarctica. Esterification yields ranged from 3 to 98%; yields seem to be linked to the electronic distribution of phenolic acids which affects the reactivity of the carboxylic function. The carbon chain length of the alcohols also plays an important role. It was observed that even for high yields, reaction times were two days or more.
