摘要
以α-呋喃丙醇为原料,经电解、酸化、氧化、水解4步合成乙基麦芽酚。利用傅里叶变换红外光谱仪(FTIR)分析鉴定合成中间体结构,其红外吸收数据与文献一致。考察了通电量、电解质、酸化条件、氧化时间、水解时间、水解温度对乙基麦芽酚收率的影响,得到适宜的反应条件为通电量2~2.5F/mol,NaBr作电解质,室温下酸化,乙醇作回流溶剂,氧化时间3h,水解时间3~4h,水解温度100℃。采用分光光度法测定乙基麦芽酚收率,最高可达62.04%。
Ethylmaltol has been prepared from 1- (2-furyl)-propanol by successive electrolysis, acid hydrolysis, oxidation and hydrolysis. The chemical structures of the intermediates were characterized by FT-IR spectra, and their infrared absorption data were in accord with the literature. The optimum conditions were found to be: quantity of electricity of 2 - 2.5 F/mol, NaBr as electrolyte, acid hydrolysis carried out at room temperature, ethanol as reflux solvent, oxidation time of 3 h, hydrolysis time of 3 - 4 h, and hydrolysis temperature of 100℃. The yield of ethylmaltol, determined by ultraviolet spectrophotometry, was 62.04 %.
