Abstract

An apparatus for the continuous reaction - separation process using supercritical CO2 as solvent has been developed. The effects of pressure and temperature on the reaction of lipase - catalyzed transesterification of methyl oleate and citronellol have been studied. The results showed that the continuous reaction - separation process in supercritical CO2 could be well carried out in the established apparatus; the initial rate of the transesterification reaction is the highest at the pressure close to the critical pressure of CO2. When the pressure is fixed at 9MPa, a maximium in conversion appears at 328K. When the temperature is varied in the range of 308K～328K with the pressure fixed at 14MPa, the initial rate increases with the temperature.
