合成了一种新的SO_4~(2-)/M_xO_y型固体超强酸——SO_4~(2-)/ZrO_2-Fe_2O_3,研究了它对正戊烷反应的活性与选择性;制备并测定了SO_4~(2-)/TiO_2固体超强酸对正戊烷的异构化活性与裂解活性及其某些物性;重复合成了文献报导的SO_4~(2-)/ZrO_2固体超强酸并测定了它对正戊烷异构化的催化性能,表明所采用的测定方法与所得结果可与文献值相比较。
A new SO_4 ~ (2 -) / M_xO_y solid superacid, SO_4 ~ (2 -) / ZrO_2-Fe_2O_3, was synthesized and its activity and selectivity to n-pentane were studied. ~ (2 -) / TiO_2 solid superacid isomerization activity and cleavage activity of n-pentane and some of its physical properties; reported in the literature of the solid superacid SO_4 ~ (2 -) / ZrO_2 repeated and determined its Catalytic isomerization of n-pentane shows that the method used and the results obtained can be compared with the literature values.
