摘要

本文报道了二氧化碳在二甲基甲酰胺中的溶解度

实验温度分别为15、20、25、30、35、40、45℃

实验压力为207.21—1684.02kPa.并且提出一个考虑了过量熵的、用溶度参数表示的活度系数方程.

Abstract

The solubility of carbon dioxide in dimethylformamide at pressures between 207.21 and 1684.02 kPa and at temperatures of 15

40 and 45℃

respectively

have been reported. An equation for the activity coefficient expressed by solubility parameters and taking excess entropy into consideration is presented in the payer.
