Abstract:
5-Hydroxymethylfurfural (HMF) and furfural (FF), two bio-based platform chemicals, were produced from various raw lignocellulosic materials (corncob, corn stover, wheat straw, rice straw and sugarcane bagasse) in a water-tetrahydrofuran media by using NaHSO4 as catalyst. The in fluences of reaction temperature (160-200 oC), reaction time (30-120 min), solvent volume ratio, feedstock concentration (2.4wt%-11.1wt%) and catalyst dosage were studied. The highest HMF and FF yields obtained from corncob were 47mol% and 56mol% under condition of 190 oC, 90 min, 10/1 of THF/H2O. Besides, the lignin in the raw biomass was also depolymerized into organosolv lignin.

摘要:
报道了在水-四氢呋喃组成的混合溶剂中,采用硫酸氢钠催化各种生物质原料(玉米芯、玉米秸秆、麦秆、稻秆和甘蔗渣)制备重要的生物质基平台化学品5-羟甲基糠醛和糠醛的研究. 考察了反应温度(160~200 oC)、反应时间(30~120 min)、水与四氢呋喃的溶剂比例(1:1~1:10)和原料质量分数(2.4wt%~11.1wt%)等反应工艺的影响.在优化的工艺条件下(190 oC, 90 min, 10:1 THF:H2O),转化玉米芯得到了47mol%的HMF和56mol%的糠醛. 此外,原料中的木质素也被有效地转化为有机溶木质素.
