脂肪醇聚氧乙烯醚合成反应的动力学研究 --环氧乙烷加成速率随时间的变化规律

从强碱催化等速率离子反应机理的理论产物分布公式出发,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式,并通过实验数据加以讨论。求出了辛醇、十二醇和十八醇的引发反应速率常数,进一步证实在M》P的情况下,环氧乙烷的耗量可作为假一级反应处理。

Study of AE Reaction Kinetics--Reaction Speed of EO Change with Time

In this paper,the point of departure is the theroitical distribution formation from the ionic reaction mech-anism of the same speed constant. We derive the relation which the consumption and reaction speed of EO change with time.and discuss the relation by means of the experimental data. We also get the speed constants of the initiat-ing reaction t octanol, dodecanol and octodecyl alcohol, and prove that the consumption of EO is first-order reaction approximatly.
