中文摘要：概述了目前世界范围内烯腈电解二聚法、丁二烯法、己内酰胺降解水解法和己二酸(ADA)催化氨化法四大类己二腈生产工艺的优缺点。着重论述了丁二烯直接氰化法的反应原理及原料现状和技术进展，指出了己二腈国产化的重要性和紧迫性。
英文摘要：It outlines the advantages and disadvantages of the current four categories adiponitrile production process of world-wide: acrylonitrile dimerization electrolysis method, butadiene method, hydrolysis degradation of caprolactam and adipic acid (ADA) catalytic ammoniting. The reaction principle, technological progress and raw material status of the direct cyanide process of butadiene are emphatically discussed. It also points out the importance and urgency of the localization of adiponitrile.
