含氟烷烃和含氟烯烃汽液平衡研究进展

Progress in Vapor-liquid Equilibrium of Fluorinated Olefins and Fluorine-containing Alkanes

综述了氢氟烃(HFCs)、氯氟烃(CFCs)和氢氯氟烃(HCFCs)3种含氟烷烃类和含氟烯烃类的汽液平衡研究进展,对文献中的实验测定及数据处理方法进行了简要分析。分析表明:研究者广泛采用静态法对汽液平衡数据进行测定,多采用PR、SRK和Lee-Kesler等状态方程,同时结合WS和vdW混合规则对数据进行关联拟合,且拟合效果较好。HFCs类汽液平衡数据的测定工作占据多数,含氟烯烃类的汽液平衡研究仍有较大的空间。

The research on vapor-liquid equilibrium of fluorinated olefins and fluorine-containing alkanes containing hydrofluorocarbons(HFCs),chlorofluorocarbons(CFCs)and hydrochlorofluorocarbons(HCFCs)was reviewed,and the methods of experimental determination and data processing were described.The results suggest that researchers extensively use the static method to measure the vapor-liquid equilibrium data,mainly adopting the equations of state such as PR,SRK and Lee-Kesler,and combine with the WS and vdW mixing rules to fit the data,which shows a satisfactory result.At present,the measurement of vapor-liquid equilibrium data of HFCs is the majority,and the research on vapor-liquid equilibrium of fluorine-containing olefins has a large space for development.
