The solubility of carbon dioxide (CO₂) in aqueous N-Methylpyrrolidone (NMP) solution has been measured by isochoric saturation apparatus. Experimental data reported under operational temperatures from (303.15 to 353.15) K and total pressures from vapor pressure of mixed solvents up to 1.3 MPa and mole fraction of NMP in mixed solvents from 0.1015 up to pure NMP. The Gibbs excess energy of mixed solvent was used for modeling of experimental data. The model with an average and maximum relative percent deviation of 2.71% and 14.61% from the number of 429 shows a sound correlative accuracy.

二氧化碳在 N-甲基吡咯烷酮水溶液中的溶解度

二氧化碳 (CO ₂ ) 在 N-甲基吡咯烷酮 (NMP) 水溶液中的溶解度已通过等容饱和装置测量。在 (303.15 至 353.15) K 的操作温度和高达 1.3 MPa 的混合溶剂蒸气压和混合溶剂中 NMP 的摩尔分数从 0.1015 到纯 NMP 的总压力下报告的实验数据。混合溶剂的吉布斯过剩能用于模拟实验数据。与 429 的平均和最大相对百分比偏差分别为 2.71% 和 14.61% 的模型显示了良好的相关精度。
