摘要
针对由甘油,1,3-丙二醇组成的体系,推算其在低压下的汽液相平衡数据。利用UNIFAC基团贡献法计算液相活度系数。提供了该二元体系于100kPa,50kPa和10kPa下的汽液相平衡数据。结果显示,两组分不会形成共沸物,而且系统压力越低,越利于它们的分离。
The vapor-liquid phase equilibrium data for the system composed by glycerol and 1,3-propanediol at low pressure are calculated. The liquid-phase activity coefficients are calculated by UNIFAC group contribution method. And the vapor-liquid phase equilibrium data of the binary system are given at the pressures of 100kPa, 50kPa and 10kPa. It indicated that the two components would not form any azeotropes. And the lower the system pressures are given, the better the binary system is separated.
