摘要
用改进的Othmer汽液平衡釜测定了101 3kPa下乙醇-水-复合溶剂6个体系在不同溶剂比下的汽液平衡数据,6种复合溶剂为:乙二醇+氯化锂,乙二醇+氯化钙,乙二醇+醋酸钾,乙二醇+氯化锂+氢氧化钾,乙二醇+氯化钙+氢氧化钾,乙二醇+醋酸钾+氢氧化钾。并用Wilson模型和NRTL模型对实验数据进行了关联,结果良好,大部分体系汽相组成平均偏差小于0 02,泡点温度平均偏差小于1K。
Isobaric VLE data for the systems ethanol-water-six mixed solvents at 101.3 kPa were measured under different ratio of solvent using a modified Othmer recirculation still, six mixed solvents are: ethanediol +LiCl; ethanediol+CaCl_2; ethanediol+KAc; ethanediol+LiCl+KOH;ethanediol+CaCl_2+KOH and ethanediol+KAc+KOH .The VLE data obtained were correlated by Wilson model and NRTL model, the results were satisfactory.
