摘要: 以乙酰乙酸乙酯和乙二醇为原料合成苹果酯。用单因素试验法和正交试验法探讨了催化剂、投料比、反应温度、反应时间和加热方式等因素对苹果酯合成的影响。试验结果表明:在微波辐照下,最佳反应条件为:以硫酸氢钠/三氯化铁为催化剂、PEG-800为相转移催化剂、乙酰乙酸乙酯:乙二醇(mol)为1∶1.5~1.8、甲苯为带水剂、微波功率为中低档、微波辐照时间为8~12min,产率可达91.5%以上。产品经IR、1HNMR、MS和GC等测定,其结果与文献值一致。

Abstract: In this paper ethyl acetoacetate and ethanediol as raw materials synthesized fructone. By a single factor synthesis and an orthogonal test, with the synthesis of fructone as study targets, the ettects of catalysts,materials ratio, temperature, time, heating ways and so on were studied. With microwave irradiation and phase transfer catalysis, the optimum reaction conditions were as follows: NaHSO4/FeCl3 as catalyst, PEG-800 as phase transfer catalyt, ethyl acetoacetate : ethanediol as 1∶1.5~1.8 (mol), methylbenzene as solvent and microwave irradiation time in 8~12 min. The yield was up to 91.5%. The synthesis product was characterized by refraction index, chemical and physical property, IR, GC, MS and 1HNMR spectra.
