多元醇和多元酚饱和液体密度的关联

摘要

In view of that there is yet no method suitable to calculate saturated liquid density for polyatomic alcohol and polyatomic phenol from litera-ture, based on revised Rackett equation and Campbell-Thodos relation, author has regressed the data of revised Rackett equation coefficient ZRA for some of common polyatomic alcohols and polyatomic phenols according to analysis on experimental data of saturated liquid density such as polyatomic alcohol and polyatomic phenol, has calculated the saturated liquid density for the 10 kinds of polyatomic alcohols and polyatomic phenols under different tempera-tures, by using of ZRA parameter data, the totally average relative tolerance is 0.562 % for 82 data.%鉴于目前文献上尚无适合于计算多元醇和多元酚饱和液体密度的方法，笔者在修正的Rackett 方程和Campbell-Thodos关系式的基础上，根据对多元醇和多元酚饱和液体密度实验数据的分析，回归出了若干常用多元醇和多元酚的修正Rackett方程常数ZRA的数据，利用ZRA参数数据，计算了10种多元醇和多元酚在不同温度下的饱和液体密度，82个数据点总平均相对误差0．562％。
