固体QR催化合成邻苯二甲酸二辛酯的研究

Solid QR Catalyst for the Synthesis of Di 2 ethyl phthalate

本文介绍了用固体催化剂QR催化合成邻苯二甲酸二辛酯(DOP)的实验方法和结果。考察了反应物配比、催化剂用量、反应时间以及催化剂使用次数对酯化反应的影响,并对产品各项质量指标进行了测定。

In this paper, a new catalyst QR for the synthesis of Di 2 ethyl phthalate is reported. Relations among the acid value, ratio of reactants, reaction time, and amount of catalyst were investigated. Besides, the catalytic activity was also discussed. At last the high quality product was obtained.
