摘要： 恒电位电解法制备己二腊可能有许多反应发生:阳极 H2O→1/2O2+2H++2e 2Br-→Br2+2e 阴极 2CH2=CHCN+2H2O+2e→2CN(CH2)4CN+2OH- CH2=CHCN+2H++2e→CH3CH2CN 2H++2e→H2 nCH2=CHCN+H2O+2e→齐聚物要使己二腈的收率有效的提高,除严格控制溶液体系的半波电位外,反应溶液体系最好是中性偏酸,即应控制pH=6-7为宜。同时,为了抑制氢气的生成,阴极材料应采用氢超电势高的铅等。
Abstract: A new approach to the electrochemical synthesis of adiponitrile is introduced. A considerably inexpensive diaphragm oell for industrial use has been designed. The cathodic polarization curves were determined. The electrclytic process was shown to have a number of advantages:easier separation,higher yield and higher purity of the product.
