本文主要介绍了近年来国外在脂肪醇乙氧基化反应催化剂方面研究与开发所取得的进展,尤其是以碱土金属化合物为主体的双组分、多组分催化体系在控制和窄化产物分子量分布方面的研究成果;分析比较了几种主要催化体系的特点;并简要评述了国外有关研究的发展趋势。
In this paper, we mainly introduce the recent progress in the research and development of fatty alcohol ethoxylation catalysts in foreign countries. Especially the two-component and multi-component catalytic systems with alkaline earth metal compounds as the main component can control and narrow the product molecular weight Distribution of the research results; analysis and comparison of several major catalytic system characteristics; and briefly reviewed the development of foreign research trends.
