摘　　要：系统地研究在不同温度、不同时间条件下,不饱和烷基酚聚氧乙烯醚和乙酰氯酯化反应的反应动力学。利用假设反应级数的方法,确定了反应级数为二级不可逆反应,得到反应速率常数,活化能45.05kJ/mol以及指前因子4.276×105 L/(mol·min),最终得到不饱和烷基酚聚氧乙烯乙酯反应动力学方程。The kinetics of esterification reaction of unsaturated alkyl phenols polyoxyethylene ether and acetyl chloride at different temperatures and time was systematically studied. Using the method of assuming reaction order, the reaction order was determined, and the reaction rate constants were obtained, the activation energy was 45.05 kJ/mol and the pre-exponential factor was 4.276×10^5 L/(mol·min).At last, the kinetic equation of the esterification reaction was obtained.
