降低生产成本和采用绿色工艺、减少环境污染一直是开发己内酰胺生产新技术的重点。其中主要有:日本旭化成开发的苯部分加氢制环己烯工艺;意大利埃尼化学公司开发的以TS-1钛硅分子筛为催化剂的肟化工艺;日本住友公司开发的气相贝克曼重排工艺;
Reducing production costs and adopting green processes to reduce environmental pollution has been the focus of developing new technologies for caprolactam production. Among them, the major ones are as follows: the partial hydrogenation of benzene to cyclohexene developed by Asahi Kasei; the oximation of TS-1 titanium-silicalite catalyst developed by Eni Chemical Company of Italy; the vapor phase Beckmann rearrangement developed by Sumitomo ;
