| 摘 要： | 以常压沸点、相对密度、相对分子质量为变量,用近年来经过严格评定的294种有机化合物共681个临界数据进行拟合,从而提出新的临界温度、临界压力和临界体积的估算式。新估算式与Joback法、Lydersen法及MXXC法等3种常用的基团贡献估算方法相比,估算精度相近,但计算过程简便。

| Abstract: | By using simple properties of pure substances—atmospheric boiling point(T_b),relative density(d 20_4)and relative molecular mass(M), a new evaluation formula group for critical properties could be achieved by fitting 681 critical properties of 294 organic compounds which had been strictly evaluated in recent years.The new method was more convenient to use than previous group contribution method and had similar estimation precision. |
