按照通常ＳＯ４２－／ＴｉＯ２固体超强酸的制备方法，分别采用四氯化钛、四烷氧基钛和钛白粉为原料合成了ＳＯ４２－／ＴｉＯ２，测定了它们在乙酸丁酯合成中的催化作用。
According to the preparation of SO42- / TiO2 solid superacid, SO42- / TiO2 was synthesized by using titanium tetrachloride, titanium tetraalkoxide and titanium dioxide as raw materials respectively, and their catalytic activities in the synthesis of butyl acetate were measured.
