摘要
利用连续管式反应器对以ＫＯＨ为催化剂的均液相月桂醇乙氧基化反应合成醇醚的动力学进行了研究，获得了其简化的动力学模型和反应速度常数ｋ。测得活化能为８２．８１ｋＪ／ｍｏｌ，比普通搅拌反应釜测得的值约高３０％，连续管式反应器所得产品的相对分子质量分布相对较窄。
The kinetics of homogeneous phase dodecyl alcohol ethoxylation for alcohol ether synthesis has been studied in the presence of KOH catalyst with a continuous tubular reactor. A simplified kinetic model and the reaction rate constant were obtained. The activation energy obtained was 82.81 kJ/mol which was about 30% higher than that obtained from stirring reactor. The molecular weight distribution of the product obtained from the continuous tubular reactor was relatively narrow.
