离子液体中磺化无定形炭催化菊糖制备5-羟甲基糠醛

Production of 5-Hydroxymethylfurfural from Inulin Catalyzed by Sulfonated Amorphous Carbon in an Ionic Liquid

研究了以1-丁基-3-甲基咪唑氯盐([Bmim]Cl)离子液体作溶剂,磺化无定形炭为催化剂催化菊糖脱水制5-羟甲基糠醛(HMF)的反应.考察了溶剂、水量、反应温度、反应时间和催化剂用量对HMF收率的影响.实验结果表明,反应温度为100°C,反应时间60min,R=5(R为水的物质的量与菊糖中所含果糖单位的物质的量的比值),m(催化剂):m(菊糖)=1:3时,HMF的收率可达50%.

The production of 5-hydroxylmethylfurfural（HMF）from inulin over sulfonated amorphous carbon was studied in an ionic liquid,1-butyl-3-methylimidazolium chloride（[Bmim]Cl）.The effects of reaction solvent,water content,reaction temperature,reaction time,and catalyst dosage on the yield of HMF were investigated.Experimental results indicated that optimum reaction conditions required a reaction temperature of 100°C,a reaction time of 60 min,an R value of 5（R represents the molar ratio of added water to fructose units in inulin）,and a mass ratio of catalyst to inulin of 1：3,affording HMF in yields of up to 50%.
