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

A Dynamic Study of the Synthesis of Polyoxyethylene Alkyl Ether --The changing rule of the reaction speed with time

本文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.

In this paper, the point of departure is the theorotical distribution formation from the ionic re action mechanism of the same speed constant. We derive the relation that the consumption and re action speed of EO change with time, and discuss the relation by means of experimental data. We also get the speed constants of the initiating reaction of octanol, dodecanol and octodecyl alcohol, and prove that the consumption of EO is a first-order reaction approximatiy.
