摘要
采用稀土元素对SO2 -4/TiO2 固体超强酸的改性 ,制备出一系列稀土固体超强酸催化剂 ,用于合成己酸乙酯的反应中 ,筛选出最佳催化剂 :SO2 -4/TiO2 /La3 + ,并研究了其合成己酸乙酯的催化活性和反应条件。
Rare earth solid superacids was prepared by chemical modifying of solid superacid with lanthanum. The catalysts were used in the synthesis of ethyl caproate.The results showed the best catalyst should be SO 2- 4/TiO 2/La 3+ . The catalyst activity and the synthesis performance were studied.
