摘要
本文以Clapeyron方程为基础,结合普遍化两项维里方程和Antoine方程,再代入Edmistcr方程式,推导出一个计算纯特质带沸点汽化热的新方程式.应用该方程式,验算了359种各类物质的常沸点汽化热.与文献中的实测值相比较,总的绝对平均误差为1.27％.
In this paper, a new equation which predicts heat of vaporization of pure compounds at normol boiling point is derived. Vaporization heat data of 359 compounds were predicted with a mean deviation 1.27% compared with the experimental data, and the predicted results are more accurate than those predicted by some others equations.
