摘要： A primary terpene alcohol such as citronellol can be enzymatically esterified with a higher fatty acid such as oleic acid in the presence of lipase in an atmosphere of supercritical carbon dioxide as the reaction medium at a high reaction velocity. The influence of the temperature and pressure of the atmosphere on the reaction velocity was studied. When the starting primary terpene alcohol is a racemic compound of the optical isomers having chirality as in (.+-.)-citronellol, efficient racemic resolution can be achieved by suitably selecting the temperature and pressure in the vicinity of the critical point of carbon dioxide to give the (S)-(-)-ester having an optical purity of almost 100% when the starting terpene alcohol is (.+-.)-citronellol.
