含二氧化硅的杂多酸催化合成丙烯酸四氢糠酯

The silica-included heteropolyacrd catalyze the systhesis of tetrahydrofurfuryl acylate

本文利用溶胶──凝胶技术将溶于水的杂多酸负载于二氧化硅基质上。实验证明，在液相反应体系中，用于合成丙烯酸四氢糖酯比只用杂多酸酸作催化剂更为有效。

Freely water-soluble heteropolyaerd conld be made insoluble through immobilization inside asilica matrix by means of sol-gel technique. Experiment verified, the silica-included heteropolyacid thusobtained catalyzed the systhesis of tetrahydrofurfuryl acylate more efficiently than the simple heteropolyacid in the liqurd-phase reaction medium.
