摘　　要：以难溶气体的吸收作为研究的基本过程,纯CO2为气体溶质,0.5M K2CO3/0.5 M KHCO3为连续相,异戊醇、苯、正己烷分别作为有机相,探索有机相对气液传质的增强作用,实验探求从不同有机相以不同油分率、表观气速对三相传质系数、增强因子等的影响。In this paper, using pure CO2 as the gas solute, the 0.5 M K2CO3/0.5 M KHCO3 as the continuous phase, isoamyl alcohol, benzene, n - hexane as a second liquid phase respectively, basing the theory of gas - liquid mass transfer, the absorption rate was calculated by the soap film flowmeter, and the absorbed quantity was measured by the sour solution method. The changes of gas - liquid rate of mass transfer and eoemeient of mass transfer were calculated in the reaction system which second liquid phase was affiliated, the reason of the change of rate of mass transfer was analyzed, and the mechanism of the enhancement of second liquid to mass transfer in gas- liquid system was discussed.
