| 摘 要： | 以间苯二甲酸二甲酯-5-磺酸钠(SIPM)和乙二醇(EG)为原料,在一定的温度和催化剂条件下进行酯交换反应制备常用聚酯染色改性剂间苯二甲酸双羟乙酯-5-磺酸钠(SIPE)。用高效液相色谱(HPLC)法测定转化率,系统研究了反应温度,时间,催化剂类型及用量,物料的摩尔配比等因素对SIPE转化率的影响。实验结果表明,获得较高SIPE转化率的最佳工艺条件为:EG/SIPM摩尔比为10.6,0.4%的Zn(Ac)2做催化剂,175℃,反应2h。

| Abstract: | The transesterification reaction prepared SIPE was conducted with SIPM and EG. The conversion rate was determined by HPLC. The influence of the synthetic technology on the transesterification rate of SIPE,such as temperature,time,catalyzer type and addition,molar ratio of EG/ SIPM were studied by HPLC. The result revealed the optimum technology is as following ： EG/SIPM molar ratio 10.6, catalyzer0.4% Zn （Ac） 2,175 ℃ ,2h. |
