SO4^2--La2O3-TiO2固体超强酸催化水杨酸的酯化反应
The Esterification of Salicylic Acid Catalyzed by Solid Super Acid SO4^2--La2O3-TiO2
摘要
Abstract
Solid super acid SO4^2--La2O3-TiO2 is first applied to esteriflcation of Salicylic Acid with methyl alcohol and acetic anbyolride. Reaction eanditions are studied. The optimum condition is in the following： molar ratio of Salicylic Acid to methyl alcohol being 1：12 ,the quantity of catalyst being 40g/mol acid, and the reaction time being 5h, the yield of Methyl Salicylate reaching over 86% ; molar ratio of Salicylic Acid to acetic anbyolride being 1：4, the quantity of catalyst being 6g/mol acid, the yield of Aacetyl Salicylic Acid could reaching over 86%. The catalyst could be easily re - cycled at least four times without the obvious loss of catalytic activity. It is an envionmentally friendly catalyst.关键词
