摘要
应用汽液双循环高压相平衡装置，测定了二氧化碳－乙醇和二氧化碳－异丙醇二元混合物分别在３０３．１５Ｋ，３１０．１５Ｋ和３２９．１５Ｋ，压力范围为１．７８～１０．０４ＭＰａ下的汽液相平衡数据。用ＤＤＬＣ－ＳＲＫ方程关联两个二元体系的汽液相平衡数据，计算值与实验值吻合良好。
Isothermal vapor liquid equilibrium data of two binary systems carbon dioxide etanol and carbon dioxide iso propanol at 303.15,310.15 and 329.15K were determined by using an apparatus with vapor and liquid alternative circulation over a pressure range from 1.70 to 10.04 MPa.Experimental data were correlated by applying the DDLC-SRK unified model based on the conformal reference state.Results show the model correlates the present data satisfactorily.
