摘要
本文以正硅酸乙酯和磷钨酸为主剂,乙醇为溶剂,采用溶胶-凝胶的方法合成了HPW/SiO_2固体强酸催化剂,通过在合成中加入助催化剂ZrO_2,考察了ZrO_2对HPW/SiO_2固体超强酸催化剂性能的影响。结果表明,助催化剂ZrO_2的加入,有效改善了催化剂的性能,催化活性得到较大的提高。
This article describes the synthesis of HPW/SiO2 by sol - gel method with ethyl silicate and phosphotungstic acid as main agents,and ethanol as solvent.The influence of ZrO2 on the performance of HPW/SiO2 is observed by adding cocatalyst ZrO2 during synthesis.The results show that the addition of ZrO2 can improve the performance of the catalyst effectively,the catalytic activity rises significantly.
