【摘要】 采用汽液双循环高压测定装置，测定了ＣＯ２与乙醚在２９８．４５Ｋ、３０８．６５Ｋ和３１８．４５Ｋ和ＣＯ２与异丙醚在２９９．１５Ｋ、３０８．６５Ｋ和３１８．４５Ｋ下，压力范围０．７２～８．３２ＭＰａ的二元汽液平衡数据。同时还测定了以上３个组分在３０８．６５Ｋ、压力在３．０４、４．０２和５．００ＭＰａ下的三元汽液平衡数据。对所测实验数据用ＤＤＬＣ－ＳＲＫ和ＳＲＫ方程进行了关联。结果表明实验数据可靠。更多还原

【Abstract】 High pressure vapor liquid equilibrium data were determined for two binary systems, i.e. carbon dioxide ethyl ether at 298.45 , 308.65, and 318.45K, and carbon dioxide isopropyl ether at 299.15, 308.65, and 318.45 K with a vapor liquid alternative circulation apparatus over a pressure range from 0.72 to 8.32 MPa. In addition, the ternary vapor liquid equilibrium data for the above three components were also determined at 308.65K under the pressures 3.04, 4.02, and 5.00 MPa respectively.All of the data measured were correlated by applying the DDLC SRK model and SRK equation of state, indicating that these data are accurate and reliable.更多还原
