摘要： 研究了在有机溶剂、合适的支持电解质和碳棒存在下,对伞花烃的直接电解氧化反应,使用GC和GC-MS方法分析测定了主要电解氧化产物,如:百里香酚甲醚、1-异丙基 4-甲氧甲基苯、枯茗醛、枯茗醇、对二甲氧甲基异丙基苯、枯茗酸甲酯、对羟基甲氧甲基异丙基苯、乙酸枯茗酯和1-二甲氧甲基-4-(1-甲氧基-1-甲基乙基)苯。详细研究了影响氧化主产物得率的主要因素,对伞花烃直接电解氧化选择性地制备枯茗醛合理的电解条件为:电解时间20～25h,甲醇/乙酸体积比10:1,氟硼酸钠作支持电解质,阳极/阴极面积比1:1,电流密度0.018A/cm2。

Abstract: Direct electrolytic oxidation of p cymene in the presence of organic solvents, appropriate supporting electrolyte and carbon rod electrodes was studied in this study.Main electrolytic oxidative products, such as, thymol methyl ether, 1 isopropyl-4-methoxymethylbenzene, cuminaldehyde, pcymen-7-ol, p(dimethoxy methyl)-isopropylbenzene, methyl 4-isopropylbenzoate, p(hydroxy-methoxymethyl)-isopropylbenzene, cuminyl acetate, and 1-(dimethoxymethyl)-4-(1 methoxy 1 methyl ethyl) benzene, were determined by GC and GC MS.Factors influencing the yield of the main oxidative product were studied in detail.Reasonable conditions for direct electrolytic oxidation of pcymene to selectively prepare cuminaldehyde are:20-25 h for electrolysis, 10:1 ratio of methanol to acetic acid, sodium fluoborate as supporting electrolyte, 1:1 area ratio of anode to cathode, 0.018 A/cm2of current density.

Key words: direct electrolytic oxidation, p-cymene, cuminaldehyde
