The present invention relates to catalytic synthesis of furan derivatives from alkoxymethylfurfural ethers or acyloxymethylfurfural esters. More particularly, the invention pertains to furan derivatives obtained by use of a multifunctional catalyst system to carry out both hydrogenation of furan starting material and hydrolysis of the reduced furan derivative in a single reaction. The process allows recovering and recycling of alcohol or acid from the reaction product.
KIT‐6. A plausible reaction mechanism was proposed after examining an independent FA decomposition reaction over the same Rh‐ED‐KIT‐6catalyst. The heterogeneity of the catalyst was verified by a hot filtration experiment. The Rh/ED‐KIT‐6 could be reused for up to three cycles without any decrease in catalytic activity and selectivity, but the slow oxidation of Rh species was detected.

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
已开发出一种清洁,简便且环境友好的催化方法,利用新型固体催化剂甲基咪唑丁基硫酸盐磷钨酸盐([MIMBS] 3 PW 12 O 40)将糠醇转化为乙酰丙酸烷基酯。固体催化剂是有机-无机杂化材料,由有机阳离子和无机阴离子组成。已经进行了优化反应条件的研究,例如反应时间,温度和催化剂负载量。在最佳条件下,高n乙酰丙酸丁酯的产率高达93%。此外,讨论了反应途径的动力学和糠醇的醇解机理。这种方法对于将基于生物质的衍生物转化为精细化学品具有环境友好性和经济性。
