摘要
用粘土合成固体超强酸．对该酸进行了结构表征、酸函数测定（－１３．１６＜Ｈ＿ｏ＜－１２．７０）及催化己二酸二辛酯的合成反应．结果表明，它的催化活性超过浓Ｈ＿２ＳＯ＿４，并且可以重复使用．
A solid superacid was synthesized with clay and characterized by XRD,FT-IR and DTA- TG etc.The Hammett acidity function H_o was determined by observing the color change of the indica-tOrs that was 13. 16<H_o< 12.70.The resultant solid superacid exhibited a higher catalytic activ-ity than thick H_2SO_4 for the synthesis reaction of dioctyl adipate, and it can be used as catalyst repeat- edly.
