摘　　要：通过对乙氧基化反应机理和反应特点、乙氧基化反应动力学模型以及脂肪醇聚氧乙烯醚(AEO系列)产品的反应动力学研究,确定了脂肪醇聚氧乙烯醚反应速率常数与反应温度的关系,为装置扩能提供了反应器基础性设计数据。结果表明:对于AEO系列的乙氧基化反应,提高反应温度有利于提高反应速率。Based on research of the mechanism,characteristics and dynamics model of ethoxylation reaction,and the dynamics of the existing 15 kt/a ethoxylated fatty alcohol ethoxylates product(AEO series),the correlation for fatty alcohol polyoxyethylene ether of reaction rate constant and the reaction temperature was confirmed,which can provide basic data for the unit expansion designed to meet the technical requirements of the reactor.The results showed that for the AEO series ethoxylation reactions,increasing the reaction temperature was favorable for the improvement of the reaction rate.
