糠酸乙酯合成的初步研究

Preliminary study on synthesis of ethyl furoate

介绍了以糠酸和乙醇为原料，以ＳｎＣｌ_４·５Ｈ_２Ｏ为催化剂、苯为带水剂合成糠酸乙酯的方法．通过试验得出最佳反应条件是：醇酸摩尔比为６：１，催化剂用量为０．７％，反应时间为４．５ｈ，带水剂苯的用量为３０ｍＬ，平均产率为９０．２％．

The new method of synthesis of ethyl furoate was reported by using α-furancarboxyic acid and ethanol as ma- terials SuCl_4·5H_2O as catalyst and benzene as dehydrating agent. The optimum reaction condition was given as follows: ratio of ethanol and acid is 6: 1, dosage of catalyst is 0.7%, reaction time is 4. 5 h and the dehydrating agent is 30 mL.The average yield is 90.2%.
