| 摘 要： | 采用恒定容积法测定了不同温度下CO2在碳酸二甲酯溶剂中的溶解度。结果表明,溶解度随压力升高而增大,随温度升高而减小。实验结果与基于正规溶液理论的PS法估算值比较符合。在相同条件下,CO2在碳酸二甲酯中的溶解度比在碳酸丙烯酯中的溶解度平均约高30%。

| Abstract: | The solubilities of CO_2 in dimethyl carbonate (DMC) were measured in a temperature range of 293.15—313.15 K and gas pressure of CO_2 up to 0.3 MPa. The result shows that the solubilities of CO_2 in DMC increase with gas pressure rise and decrease with temperature rise. The measured values are reasonably agreed with those calculated by Prausnitz-Shair method based on the normal solution theory. At the same condition, solubilities of CO_2 in DMC are 30% higher than those in propylene carbonate. |
