硫酸根助氧化铬体系超强酸
Sulfate Promoted Chromium(Ⅲ) Oxide Superacid
【摘要】 制备了Cr2O3和Cr(OH)3,用(NH4)2SO4对其活化做成超强酸,并以IR、XPS和正戊烷转化对超强酸进行了表征.结果显示,Cr(OH)3硫酸化后的酸性比硫酸化的Cr2O3强。
【Abstract】 The present paper covers the preparation of Cr2O3 and Cr(OH)3 and their transformation into superacids by addition of SO4-·SO42-/Cr2O3 and SO42-/Cr(OH)3 were characterized by means of IR, XPS and the conversion of n-petane. The results showed that the acidity of sulfated Cr(OH)3 is stronger than that of sulfated Cr2O3.
