The Synthesis of Butylparasept by Heteropolyacids The Synthesis of Butylparasept by Heteropolyacids Catalysis
【摘要】 以杂多酸HPA为催化剂,由对羟基苯甲酸和丁醇制备对羟基苯甲酸丁酯,研究了最佳反应条件,与硫酸相比,催化剂用量少,反应时间短,产率高,酯收率可达到96%以上。
【Abstract】 The esterification of butanol and phydr-oxybenzoic acid catalyzed by heteropolyacids(HPA),we have studied this reaction best conditions.Comparing with sulfate acid,the amount of HPA is smaller;reactive time is shorter;the yield of ester is higher.The yield have been over 96%.
