摘　　要：己二腈是一种重要的有机化工中间体,主要用于合成尼龙66、HDI、尼龙610等材料,生产方法主要有丁二烯氰化法、丙烯腈电解法、己二酸氨化法3种。虽然己二酸氨化法不是3种方法中最先进的,但由于近期己二酸市场价格持续低迷,该技术又一次引起业内投资的关注。简述了己二酸氨化法制备己二腈的技术优缺点及近期的研究进展,并简单分析了该路线具有的优势。Adiponitrile is a kind of important organic chemical intermediate,mainly used in synthetic materials such as nylon 66,HDI,nylon 610.Its main three kinds of product methods are butadiene cyanidation,acrylonitrile electrolysis and adipate ammonification.Though the adipate ammoniation method the most advanced,due to the recent low price of adipic acid,the technology once again aroused the concern of the industry investment.The advantages and disadvantages of the adipate amination method and the recent research progress were briefly described and analgzed.
