摘要
评述了以芳烃原料生产己内酰胺工业技术在寻求经济工艺步骤、降低副产物等研究和应用进展 ,重点介绍了环己酮制备、氨肟化、多级Beckmann重排、苯甲酸加氢、酰胺化 -重排组合工艺和精制等过程的技术改造 。
Technical progress at economical routes and low byproduct in preparing caprolactam from aromatic hydrocarbon feedstocks are reviewed. New processes such as oxidation, ammoximation, multi-stage Beckmann rearrangement, hydrogenation of cyclohexanecarboxylic acid, nitrosation-rearrangement combined process and purification are introduced, and their pros and cons are discussed as well.
