摘要
研究了茴香脑电氧化合成茴香醛的最佳条件:以乙醇和水(5:1(V/V))为溶剂,以含1.9%茴香脑和1.6%NH_(4)NO_(3)(支持电解质)的乙醇溶液作阳极液;不含茴香脑的混合溶液为阴极液。溶液pH=1~2,池温25~28℃,控电流(10mA/cm^(2))电解,电流效率60~62%,反应总级数n=1。
We studied the optimum conditions for the synthesis of anisaldehyde from anethole by elec-trooxidation.Thus,a mixture of alcohol and water(volume ratio 5:1)was used as solvent.The anode liquor contained 1.9%of anethole and 1.6%of ammonium nitrate(supporting electrolyte),and the cath-ode llquor did not contain anethole.In the electrolytic solution pH=1~~2,the cell temperature was 25~28℃.In the electrolytic process,the current was controlled at 10mA/cm^(2),and the current efficiency achíeved 60~62%.Total order of the reaction is equal to one.
