槽外式在线超声间接电合成苯甲醛／对甲基苯甲醛的工艺改进
Improvement of Process for Out_cell Indirect Electrosynthesis Benzaldehyde/p_Methylbenzaldehyde with Online Ultrasound
摘要
Abstract
In view of the excessive reaction volume and low current efficiency appearing in the conventional out_cell indirect electrosynthesis process ,on_line ultrasonic heterogeneous electroly_sis and drop_by_drop addition of high_concentration oxidation solution were adopted to optimize the synthesis process for the production of benzaldehyde and its derivatives .T he improved process was easy to operate ,the conversion rate of Mn (Ⅱ) was over 96.73% ,the current efficiency was 85.01% ,the obtained high concentration Mn (Ⅲ) could be directly used without dilution ,which effectively reduced volume of reaction solution at least 200% with respect to the traditional process and halved the amount of organic ingredients .The process greatly saved the amount of raw materials and equipment space ,and solved the problems of low reaction efficiency caused by the excessive reaction solution volume ,the yield of benzaldehyde and p_methyl benzaldehyde reached 77.14% and 92.52% respectively in the improved process .关键词
