SO_(4)^(2-)/M_(x)O_(y)型固体超强酸催化剂研究(Ⅰ)

Study on Solid Super Acid Catalyst of SO_(4)^(2-)/M_(x)O_(y) Type

合成了一种新的SO_(4)^(2-)/M_(x)O_(y)型固体超强酸——SO_(4)^(2-)/ZrO_(2)-Fe_(2)O_(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-)/ZrO_(2)-Fe_(2)O_(3) solid super acid had been synthesied and iis composition and catalytic properties were systematically studied.According to its IR data, the acid site of producing super acid was discussed and a new viewpoint was suggested, the data 1040-1080, 1130-1150, 1200-1280cm-1 were considered as its three characteristic IR adsorption peaks.The catalytic properties and characteristics of SO_(4)^(2-)/TiO_(2) solid super acid were also systematically studied.
