| 摘 要： | 本文研究了在H型强酸性阳离子交换树脂存在下,邻苯二甲酸酐及顺丁烯二酸酐与乙二醇的酯化反应动力学。结果表明:在H型强酸性阳离子交换树脂存在下,上述反应的动力学过程不能用Lin在液体酸催化时的动力学方程—dCOOH]/dt=k″(COOH)~2来表示,但与动力学方程—dCOOH]/dt二k(k_h+k′_h)COOH]OH]~2则有很好的一致性。

| Abstract: | kinetics studies of polyesterification of ethylene glycol and dibasic acid(maleic anhdride and phthalic anhydride) over H-type strong acid resin were investigated.The kinetic processes can not be expressed by Lin's equation -dCOOH]/dt = k"GOOH)2, with which liguid acid catalysis was agreed, but agreed very well with the eguation-d COOH]/dt=k |
