摘要

含二氧化碳、环氧单体和溶剂的聚合反应系统

压力是一个重要参数

是研究该类系统的汽液平衡和动力学所必需的

通常反应在接近临界温度的情况下进行

二氧化碳因压缩和溶解作用部分液化

其压力不能简单地用气体方程估计

而要依靠实验测定。但是作者在研究反应体系相平衡和动力学的规律时发现

如果反应是在规定温度和投料配比的情况下进行的

则系统的压力可以用已知的参数计算出来。

Abstract

For the multi - phase systems involving CO2

the pressure p can be estimated from the temperature

the weight of CO2

and the volume not occupied by materials other than CO2. An empirical equation is introduced

by which the standard deviation for p calculation is 10.4 % for 11 systems. The accuracy can be improved by considering different solubility of CO2 in various liquid components. By this means

the pressure p can be determined with a standard deviation of 5.39 % . Thus the vapor- liquid equilibrium and kinetic parameters can be obtained without experimental measurements. Further

the copolymerization process of CO2 and propylene oxide can be simulated satisfactorily.
