摘要:

通过对间接电氧化制苯甲醛过程中电解温度、酸浓度原料摩尔浓度以及氧温度等因素进行考察,得到了最佳工艺条件.即电解条件为:硫酸浓度8.0 mol·L-1,温度323 K;甲苯氧化条件为:硫酸浓度8.0 mol·L-1,温度333 K.不仅使间接电氧化工艺中的电解与氧化两个阶段保持了酸浓度的一致,而且使电解过程的电流效率增加了13.22%左右,甲苯氧化反应的苯甲醛产率增加了6.67%左右.

Abstract:

The optimal process conditions were obtained by investigating the electrolytic temperature, acid concentration, molar concentration of raw materials and oxygen temperature in the process of indirect electrooxidation to benzaldehyde. That is, the electrolysis conditions are: sulfuric acid concentration 8.0 mol· L-1, temperature 323 K; The oxidation conditions of toluene were: sulfuric acid concentration 8.0 mol· L-1, temperature 333 K. not only keeps the acid concentration consistent in the two stages of electrolysis and oxidation in the indirect electrooxidation process, but also increases the current efficiency of the electrolysis process by about 13.22%, and the benzaldehyde yield of the toluene oxidation reaction increases by about 6.67%.
