利用新型固体催化剂甲基咪唑烷基硫酸丁酯磷钨酸盐（[MIMBS]₃PW₁₂O₄₀），开发了一种清洁、简便、环保的糠糠醇转化为乙酰丙酸烷基酯的催化方法。固体催化剂是一种有机-无机杂化材料，由有机阳离子和无机阴离子组成。对反应时间、温度、催化剂负载等条件进行了优化研究。在最佳条件下，乙酰丙酸正丁酯的收率可达93%。讨论了糠醇醇解反应的动力学过程和机理。这种方法是环境友好和经济的生物质衍生物转化为精细化学品。
A clean, facile, and environment-friendly catalytic method has been developed for the conversion of furfuryl alcohol into alkyl levulinates making use of the novel solid catalyst methylimidazolebutylsulfate phosphotungstate ([MIMBS]₃PW₁₂O₄₀). The solid catalyst is an organic-inorganic hybrid material, which consists of an organic cation and an inorganic anion. A study for optimizing the reaction conditions such as the reaction time, the temperature and the catalyst loading has been performed. Under optimal conditions, a high n-butyl levulinate yield of up to 93 % is obtained. Furthermore, the kinetics of the reaction pathways and the mechanism for the alcoholysis of furfuryl alcohol are discussed. This method is environmentally benign and economical for the conversion of biomass-based derivatives into fine chemicals.
