【摘要】 本文用１２－钨磷酸（ＨＰＷ）作为对羟基苯甲酸与正丁醇酯化合成尼泊金丁酯的固体催化剂。研究了不同的载体及制备方法、醇酸配比对酯收率的影响。初步考查了催化剂的稳定性。回流吸附法制备的ＨＰＷ／活性炭具有酯收率高、稳定性好、不易流失等优点。更多还原

【Abstract】 In this paper,12-tungstophosphoric acid is used as solid catalyst for the esterification d butanol and p-hydroxybenzoic acid.The effect of such factors as different carrier,different synthesis technology and the ratio of butanol to the acid, on the yield of the ester have been studied. The stability of catalyst have been investigated preliminarily.更多还原
