| 摘 要： | 提出了以α-呋喃丙醇为原料,TS-1作催化剂,H2O2作氧化剂制备乙基麦芽酚中间体的新方法。中间体经苷化、氧化、水解步骤合成乙基麦芽酚。考察了溶剂、催化剂用量、氧化温度、氧化时间、苷化条件、pH值对乙基麦芽酚收率的影响,得到适宜的反应条件为:氧化温度40℃,氧化时间12h,苷化温度75℃,pH为8,氧化3h,水解温度100℃,水解时间3h,乙基麦芽酚最高收率可达57.4%。

| Abstract: | A novel method for the synthesis of an intermediate in the production of ethylmaltol has been developed using 1-(2-furyl)-propanol as the raw material,TS-1 as a catalyst,and H2O2 as oxidant. Ethylmaltol has been prepared from the intermediate by glycosidation,oxidation and aqueous hydrolysis. The factors affecting the yield of ethylmaltol are discussed,including the choice of solvent,amount of catalyst,reaction temperature,reaction time,glycosidation conditions and its pH. The optimum reaction conditions we... |
