摘　　要：采用自制L&B酸催化剂制备毛醛,通过加入碱洗剂碱洗,复配阻聚剂精制过程,提高反应的选择性,抑制糠醛精制过程中的聚合反应,解决糠醛收率低的问题。通过正交实验,考察各实验因素对实验指标的影响发现玉米芯制备毛醛的最佳实验条件为:催化剂浓度6%、自制L&B酸催化剂用量为玉米芯量的30%、反应时间为120 min、反应温度为150~160℃。该工艺避免了过度氧化、炭化结焦和二氧化硫气体排放问题,具有精制率和原子利用率高的优点。The self-made L&B acid catalyst wa s used to prepare hair aldehyde,and the process of adding alkali detergent for alkali washing and compounding polymerization inhibitor refining process improves the selectivity of the reaction,inhibits the polymerization reaction in the furfural refining process,and solves the problem of low furfural yield.Through orthogonal experiments,investigating the influence of various experimental factors on the experimental indicators,it was found that the best experimental conditions for preparing corncobs are:catalyst concentration 6%,self-made L&B acid catalyst dosage was 30%of the corncob amount,reaction time 120 min,reaction temperature was 150~160℃.
