Direct conversion of biomass-derived xylose and furfural into levulinic acid, a platform molecule, via acid-catalysis has been accomplished for the first time in dimethoxymethane/methanol. Dimethoxymethane acted as an electrophile to transform furfural into 5-hydroxymethylfurfural (HMF). Methanol suppressed both the polymerisation of the sugars/furans and the Aldol condensation of levulinic acid/ester.
首次在二甲氧基甲烷/甲醇体系中通过酸催化将生物质衍生的木糖和糠醛直接转化为平台分子乙酰丙酸。二甲氧基甲烷作为亲电试剂将糠醛转化为5-羟甲基糠醛(HMF)。甲醇既抑制了糖/呋喃的聚合反应,也抑制了乙酰丙酸/酯的羟醛缩合反应。
