摘要
以米糠为原料,采用超临界CO2流体萃取技术,对其中的糠蜡进行提取精制,再以丙酮作为溶剂索氏提取二十八烷醇.通过正交实验,确定超临界CO2流体萃取糠蜡的最佳参数为:压力50MPa,温度40℃,时间50min.
The extraction and purification of rice bran wax by SFE- CO2 extraction from the rice bran and furthermore obtaining zetacosanol by dissolving it in the acetone solvent were studied in this dissertation. The result of orthogonal experiment is flint the optimum parameters of wax from rice bran by SFE - CO2 extraction are pressure 50MPa, temperature 40℃ and time 50min.
