卤代烃类物质维里系数的理论与实验研究

CFC和HCFC的绿色替代物大多属于卤代烃类物质，其热物性研究是国际上的研究热点，到目吧形醇哉饫辔镏饰锵凳南低逞芯浚锵凳难芯烤哂兄匾睦砺垡庖搴褪涤眉壑怠１鞠钅磕獠捎猛臣迫攘ρХ椒ㄑ芯科湮锵凳睦砺勰Ｐ秃头肿邮颇懿问岢鱿嘤Φ奈锵凳す婪匠蹋⒍孕鹿ぶ蔋FC-227ea的维里系数进行实验研究。

Because halogenated carbons have various purposes in industry and engineering, their thermophysical properties are very important and are widely studied. In this project, based on the analysis about the principle and technique for thermodynamic property measurements of fluids, a series accurate experimental data of thermodynamic properties, such as PVT property, speed of sound, surface tension and vapor pressure, for some new halogenated carbons were obtained, and their virial coefficients were also drived and correlated. Especially distinguished progress was gotten in the thermodynamic property studies for 1,1,1,2,3,3,3-hepatafluoroparopane (HFC-227ea). The correlation and prediction of surface tension for halogenated carbons were also studied
