摘要
利用Rose-Wiliams汽液双循环等压平衡釜测定了二元体系R142b-DMF及三元体系R22-R142b-DMF的汽液平衡数据。并分别用UNIFAC模型和UNIFAC-MH81基团贡献型状态方程作了关联和预测,结果符合得较好。
Gas Liquid Equilibrium of binary system R142b DMF and ternary system R22 R142b DMF is measured by means of Rose Williams gas liquid doublerecycling isobaric equilibrium still.Furthermore,the correlation and prediction are made by using UNIFAC model and UNIFAC MH81 group contribution equation of state,the results of which are in good agreement.
