Abstract:

Adiponitrile was produced through the electroreduced coupling of acrylonitrile in a cell employing dimensionally stable anode(DSA)as anode and Cd or Pb as cathode without diaphragm.Under the optimized conditions，electroredutive coupling of acrylonitrile for 48 h，the yield of adiponitrile and total efficiency are up to 85.7% and 86.6% in the DSA-Cd cell; 80.1% and 77.7% in the DSA-Pb cell.Since DSA is possessed of excellent anti-corrosion，employing DSA as anode for electro-synthesis of adiponitrile is one of the favorable selections.

摘要：

用形稳阳极（DSA）作阳极，镉或铅为阴极，在无隔膜式电解槽中进行丙烯腈二聚电还原生成己二腈。在优选的电解条件下，DSA-Cd电池中，己二腈的产率达85.7%，总电流效率为86.6%，DSA-Pb电池中，己二腈的产率达80.1%，总电流效率为77.7%。鉴于DSA优越的耐腐蚀性，其可作为己二腈电合成阳极材料的一种良好的选择。
