Abstract
The conversion of biomass-derived levulinic acid (LA) into gamma-valerolactone (GVL) using formic acid (FA) and Fe3(CO)12 as the catalyst precursor was achieved in 92% yield. To mimic a biorefinery setting, crude liquor (containing 20% LA) from the acid hydrolysis of sugarcane biomass in a pilot plant facility was directly converted into GVL in good yield (50%), without the need for isolating LA.
摘要
使用甲酸（FA）和Fe₃(CO)₁₂作为催化剂前体，可将生物质衍生的乙酰丙酸（LA）转化为γ-戊内酯（GVL），产率达92%。为模拟生物精炼环境，在中试工厂设施中，甘蔗生物质酸水解得到的粗液（含20% LA）可直接高效转化为GVL（产率50%），无需分离LA。
