摘    要:利用红外光谱(IR)研究了槽外合成对甲氧基苯甲醛的反应机理,结果证明:对甲基苯甲醚先氧化成对甲氧基苯甲醇,再氧化成对甲氧基苯甲醛并最终氧化成对甲氧基苯甲酸。间接电合成对甲氧基苯甲醛的优选条件:原料配比为n(Ce4+)∶n(p CH3O-C6H4-CH3)=4∶3;反应温度为30℃;对甲氧基苯甲醛反应收率为96.8%。

关 键 词:对甲氧基苯甲醛  对甲基苯甲醚  间接电合成  反应机理

Abstract:The mechanism of outside cell reaction of electrosynthesis of p-methoxybenzaldehyde was studied by Fourier-transform infrared (FTIR) absorption spectra. The results show that the reaction of Ce~(4+) with p-methoxytoluene reveals that the reaction proceeds in well-defined separated steps from p-methoxybenzyl alcohol,to p-methoxybenzaldehyde and eventually, to p-methoxybenzoic acid. The optimum conditions of outside cell reaction are as follows: (n(Ce~(4+))∶n(p-CH_3O)(C_6H_4)(CH_3)=4∶3); temperature: 30 ℃. The reaction yield of p-methoxybenzaldehyde is 96.8%.
Keywords:p-methoxybenzaldehyde  p-methoxytoluene  indirect electrosynthesis  mechanism
