| 摘 要： | 采用间二甲苯和CO为原料、粉状无水AlCl3为催化剂，利用羰基化反应在反应温度-20℃，CO压力1．5MPa，反应时间50分钟，n（AlCl3）：n（间二甲苯）=1．0：3．0的较佳工艺条件下，合成的羰基化中间δ-络合物经水解、干燥、减压蒸馏可以得到2，4-二甲基苯甲醛，产率（相对催化剂AlCl3的摩尔数）≥83．0％。

| Abstract: | 2,4-dimethylbenzaldehyde was synthesized from m-xylene and CO as the raw materials under the catalysis of powdery and anhydrous AlCl3 under the optimum reaction conditions that the reaction temperature was -20℃, CO pressure was 1.5 MPa, the reaction time was 50 minutes, and n （AlCl3） ： n （m-xylene） =1.0：3.0, the intermediate product of carbonylation, δ-complex was subject to hydrolysis, drying and distillation under reduced pressure, thus giving 2,4-dimethylbenzaldehyde with a high yield （based on the moles of the catalyst, AlCl3） above 83.0%. |
