摘　　要：蜂蜡高压皂化水解后用超临界CO2萃取制得高级脂肪醇。最佳皂化条件为:皂化温度150℃,皂化时间4 h;超临界CO2萃取的最佳条件为:萃取温度60℃,压力25 MPa,时间2 h。高级脂肪醇的得率为63.11%。A new technological process for extracting higher fatty alcohol from bees wax by supercritical CO2 extraction is described. The optimum supercritical conditions are as follows：saponification temperature is 150 ℃, saponification time 4 h. The optimum conditions of supercritical CO2 are as follows：extraction pressure is 25 MPa, extraction temperature is 60 ℃, extraction time is 2 h, the yield of high fatty alcohols is 63.11%.
