| 摘 要： | 通过乙二醇单乙醇和醋酸的酯化反应，研究了微波辐照对酯化反应的作用机理．利用微波辐照与常规加热两种方法，对介质回流温度前后两个阶段反应的结果作了对比，从而得出微波对酯化反应有明显的加速作用，其加速作用实质是提高反应介质的升温速率．在实验条件下，微波提供给反应体系的能量是热能．

| Abstract: | The mechanism of esterification irradiated by microwave was studied by using the synthetization system of 2-Ethoxycthyl acetate with the catalyst of H2SO4 Compared the irradiation by microwave to the conventional heating, it was demonstrated that the rate of esterification of 2-Ethoxyethyl Acetate had been obviously accelerated by microwave due tO raising the rate of increase in temperature since microwave;upplied a great amount of heat energy to the reaction system. |
