摘要
提出一个统一的关联方法 ,将常压沸点附近的部分数据同极微压范围的实验点数据一起关联 ,以三常数的Antoine方程为重点 ,选用四常数的Riedel方程、Frost Kalkwarf Thodos方程、Miller方程以及经验性改进的Antoine方程作为参考方程 ,考察。
A united correlation method was proposed for correlating vapour pressure of pure substance with temperature.This method was mainly based on the three constant Antoine equation,with other four constant equations,including Riedel,Frost Kalkwarf Thodos,Miller and empirically modified Antoine equation,used as reference equations.By using this approach,the data of some alkanes and aromatic ester was correlated in wide range covering extremely low vapour pressure.The correlated results by Antoine equation indicate that the average deviations between the calculated and experimental value are about 3.5%～8.7%.The values of the three parameters in Antoine equation are presented for these substances.
