Synthesis of Salts of 4-methyl Pyridine Heteropoly Acid and Research on Their Catalytic Performance of the Esterification
摘要
Abstract
Three different salts of 4-methyl pyridine heteropoly acid were synthesized by 1-(3-sulfonic acid group) propyl-4-methyl pyridine reacting with phosphotungstic acid, phosphomolybdic acid and silicotungstic acid. Their catalytic performance was studied by synthetic reaction of the nipagin ethyl esters. The experiments showed that three types of salts of 4-methyl pyridine heteropoly acid all have the ability of reaction-controlled phase-transfer and that 1-(3-sulfonic acid group) propyl-4-methyl pyridine phosphotungstate has the best phase-transfer perfor⁃mance. When using 1-(3-sulfonic acid group) propyl-4-methyl pyridine phosphotungstate as catalyst, n(acid):n(al⁃cohol): n(catalyst)=3:1:0.03, reaction time for 8h, reaction temperature at 120 ℃ , the yield of nipagin ethyl ester can be achieved to 87.7%.关键词
