摘　　要：研制了固体超强酸催化剂S2O82-/ZrO2-M2O3(M=Al,Fe),并以赤砂糖为原料,催化水解法制备5-羟甲基糠醛。通过单变量法考察了催化剂的焙烧时间、赤砂糖浓度、反应温度、反应时间、催化剂的用量等对5-羟甲基糠醛相对收率的影响,并采用了正交实验来确定最佳工艺条件。研究结果表明:当催化剂的焙烧时间为120min、赤砂糖浓度为10 g/L、反应温度为200℃、反应时间为40 min、催化剂用量为赤砂糖量的15%时,5-羟甲基糠醛相对收率最大,达到41.43%。With brown granulated sugar as the raw material,5-hydroxymethyl furfural were prepared by using S2O82-/ZrO2-M2O3（M=Al,Fe） as a solid superacid catalyst.The effect of technological condition,such as catalyst calcination time,brown granulated sugar concentration,reaction temperature,reaction time,catalyst dosage,on the relative yield of 5-hydroxymethyl furfural is investigated.Orthogonal experiment is adopted to determine the optimal condition.The result shows that the best relative yield of 5-hydroxymethyl furfural is 41.43% under the optimal condition： the catalyst calcination time of 120 mins,brown granulated sugar concentration of 10 g/L,reaction temperature of 200 ℃,reaction time of 40 mins,and the catalyst dosage of 15%.
