摘要
在乙醇-盐酸溶液中以Pb为阴极,电解还原对硝基氯代苯以合成对抗苯胺。阴极液:70mL的乙醇-盐酸溶液加1.0g对硝基氯代苯,温度:70±1℃,电流密度:4.6A/dm ̄2,电量:理论电量的120%时,对氯苯胺的最大产率达96.2%。
Electrolytic reduction of 4-nitrochlorobenzene(Ⅰ)to 4-chloroaniline(Ⅱ)at a lead cathodewas conducted in ethylalcohol-HCI solution. Amaximum yield of 96.2 per cent of(Ⅱ)was obtained.Optimum conditions were cathode solution 70 mL ethylacohol-HCI + 1.0g(Ⅰ),temperature 70±1 ℃,cathodic current density 4.6A/dm ̄2 and current passed 120 per cent of theory。
