摘要
以０．０１ｍｏｌ对甲苯磺酸和５ｍｌ３０％过氧化氢作催化剂，在苯或甲苯中０１ｍｏｌα呋喃甲酸和０５～０１２ｍｏｌ脂肪醇回流反应３ｈ，以８０％～９５６％的收率合成了７个糠酸烷基酯。结果表明酯的收率普遍提高。
The seven alkyl esters of αfuroic acid were synthesized in the yields of 80% to 95.6% by refluxing the solution of benzene (or toluene) containing 0.1 mole αfuroic acid and corresponding aliphatic alcohols (0.12～ 0.5mole ) for 3h in the presence of ptoluenesulfonic acid (0.01 mole) and 5ml hydrogen peroxide of 30%.Experimental results indicated that the yields of αfuroic esters were enhanced in the above esterifications by using hydrogen peroxide and ptoluenesulfonic acid as catalyst.
