摘要
评述了近年来国外在聚酰胺生产中出观的新技术路线中的关键步骤——苯部分加氢生成环己烯、环己烯水合生成环己醇及环己烯一步氧化直接生成环己酮。简介了环己酮直接氧化制己内酰胺的发展趋势及尼龙-66生产原料路线的开发动向。
The key industrial steps in the new polyamide production processes abroad in recent years, such as partial hydrogenation of benzene to cyclohexene, hydration of cyclohexene to cyclohexanol and direct oxidation of cyclohexene to cyclohexanone, are reviewed. The trends of direct oxidation of cyclohexanone to hexanolactam and developments of different routes in preparation of feed stocks of nylon-66 are also described.
