摘　　要：以水-1,4-二氧六环为双相体系,催化果糖制取5-羟甲基糠醛,研究催化剂种类、反应时间、反应温度、水相体积、原料与催化剂比例、催化剂循环使用等不同因素对果糖制取5-羟甲基糠醛的影响。结果表明:当采用NaHSO;为催化剂、反应温度为140℃、反应时间为1 h时,5-羟甲基糠醛产率达到最高值,为83%。进一步探究以葡萄糖、纤维素为原料制备5-羟甲基糠醛的产率,分别为50%和30%。催化剂经4次重复使用后仍保持良好的催化活性。Taking water-1,4-dioxane as two phase solvent,5-hydroxymethylfurfural(HMF)is produced by fructose dehydration. The effects of catalyst type,reaction time,reaction temperature,volume of water phase and ratio of raw material to catalyst,catalyst cycling on the preparation of 5-HMF are studied. The results show that the highest yield of HMF is 83% when taking NaHSO;as catalyst,reaction temperature 140 ℃ and reaction time 1 h. The yield of HMF from glucose and cellulose conversion is 50% and 30%,respectively. After 4 times of reuse,the catalyst still has good catalytic activity.
