【摘要】 在系统整理大量临界数据的基础上，提出了临界性质的新基团估算法及基团贡献值，ＴＣ、ＰＣ、ＶＣ的平均误差分别为０．７６、４．２５、２．３３％，此结果优于作为比较的Ｊｏｂａｃｋ法。此外，本法还可用于长链化合物更多还原

【Abstract】 New group contribution correlations, which are based on systematical evaluation of critical data, for estimating critical properties have been proposed with contribution values of groups. The average deviations of T C,P C,V C are 0.76%, 4.25% and 2.33%respectively, and that are lower than those by Joback′s method chosen for comparison. In addition, this method can be used for longer chain compounds.更多还原
