摘要 使用气相色谱对离子液体中的对二甲苯的无限稀释活度系数进行测定并归纳出估算式,同时进一步分析了实验中的误差,确信估算值在(100±2.7)%,为今后对二甲苯在离子液体中的分离方法的建立提供可靠数据. The activity coefficients at infinite dilution of P-xylene in ionic liquid were measured by using gas-liquid chromatography and the estimative formula was summed up. At the same time the error of the experiment was analyzed. It is convinced that the estimative data is (100±2.7)% and it supplies dependable data in order to establish separation method of P-xylene in ionic liquid for the future.
