Abstract: The molecular thermodynamic model of gas solubility in non-polar solvents established by Hu, Xu and Prausnitz was extended to polar solvent systems. Henrys constants of various gases in water, alcohols, ketones, halo-genated aromatics and naphthalene substitutes are calculated. For all of 81 systems with 13 solvents whose maximum dipole moment is 2.83 Debye, satisfactory results are obtained with the use of only one adjustsble para-meter over a wide temperature range of 193.15-573.15K.

摘要： 本文将胡英、徐英年、Prausnitz建立的气体在非极性溶剂中溶解度的分子热力学模型推广到极性溶剂系统,并用它计算了气体在水、醇、酮、卤代苯及萘的取代物中的Henry常数.在193.15—573.15K的广阔温度范围内,对于分子偶极矩最大为2.83德拜(Debye)的13种溶剂、共81个系统,一般只用一个可调参数,本模型均得到较好的计算结果.
