摘　　要：本文在前文基础上,从强碱催化非等速率离子反应机理的产物分布公式出发,推导出反应过程中环氧乙烷耗量及加成速率随时间变化的关系方程,并通过实验数据加以讨论,结果表明,本文推导出的关系方程从动力学角度能够较好地反映乙氧基化反应的真实规律。This paper bases on our works in the past. The point of departure is the theroitic-al distribution formation from the ionic reaction mechanism of the different speed constants. we derive the relation which the consumption of EO changes with time, and discuss the relation by means of the experimental data. The results show that this relation can comparatively effect the true rule of the reactionsof alcohol and EO from the dynamics angle.
