摘要
以二甘醇和苯甲酸为原料,对甲苯磺酸为催化剂,合成二甘醇二苯甲酸酯(DEDB),用作聚氯乙烯(PVC)主增塑剂。实验研究表明,其工艺方法简单可行,收率大于90%。该新工艺制品物性指标完全符合SG76-73标准,性能接近邻苯二甲酸二辛酯(DOP)增塑剂。
The Diethylene Glycol Dibenzoate(DEDB) as the main plasticizer of polyvinyl chloride(PVC) is composed by Diethylene and Benzene monocarbonic acid under the catalyst with P-methyl Benzene sulfonic acid.The Experiment research indicates that the method is simply workable and the receiving rate is more than 90%.This new technology products fits completely the standards of SG76-73.The function is close with DOP.
