摘　　要：合成了纳米固体超强酸,考察了该催化剂在柠檬酸三丁酯合成中的催化活性,并与非纳米的SO42-/TiO2,SO42-/ZrO2,SO42-/Fe2O3,浓H2SO4催化剂进行了比较,同时对酯化反应的几种影响因素进行了研究.The nanosolid superacid SO42-/Fe2O3 was synthesized and its catalytic activity for the synthesis of tri-n-butyl citrate was also studied. The catalytic activity was compared with the catalytic activity of SO42- /TiO2,SO42- /ZrO2,SO42- /Fe2O3 and H2SO4. The influence of esterification such as the synthesis of catalyst and the adding amount of the catalyst, the factors of esterifying time were also investigated.
