摘要：
The ester synthesis from oleic acid and (+/-)-citronellol by lipase was carried out in supercritical carbon dioxide(SC-CO2). In the near-critical region, the rate of reaction was considerably enhanced and (S)-(-)-oleic acid 3,7-dimethyl-6-octenyl ester was stereoselectively formed. The results were discussed with taking account of solvent properties of SC-CO2 and aggregation phenomenon about reacting species at high pressures.
