摘要
以廉价金属硫酸盐为催化剂,在γ-戊内酯/水复合溶剂中催化半纤维素定向转化制备糠醛,糠醛得率高达50.2%,半纤维素液化转化率达95.5%。在γ-戊内酯/水复合溶剂中,以金属硫酸盐为催化剂进一步研究了直接催化木质纤维生物质原料玉米芯和竹粉定向转化制备糠醛,其中糠醛得率分别达39.5%、29.7%,木质纤维原料液化转化率分别达86.5%、80.5%。
Furfural was prepared from hemicelluloses and lignocellulosic biomass in the presence of theγ-valerolactone/water solvent system with low cost sulfate as catalyst.The yield of furfural could be obtained as high as 50.2%,accompanying with 95.5% of hemicellulose conversion.Furthermore,furfural also could be prepared from real lignocellulosic biomass corncob and bamboo meal in the above catalytic system with the yield of 39.5% and 29.7%,respectively.In this case,corncob and bamboo meal conversion could be 86.5% and 80.50%.
