纺织导报:现阶段国内外己内酰胺的技术发展情况如何?骆红静:目前,世界工业化生产己内酰胺的主流生产工艺为两种:(1)以环己酮肟贝克曼重排为基础的环己酮-羟胺路线。DSM/HPO工艺及AlliedSignal(现为Honeywell)工艺为其代表性工艺。前者原料为苯,后者原料为苯酚;(2)SNIA(甲苯路线)及东丽(光亚硝化路线)工艺是另外两种不同的工艺,其中甲苯法目前仅中国有一套装置。
Textile Review: How is the Technical Development of Caprolactam at Home and Abroad? Luo Hongjing: At present, there are two mainstream production processes for industrialized production of caprolactam in the world: (1) Cyclohexanone-hydroxylamine based on Beckmann rearrangement of cyclohexanone oxime route. DSM / HPO process and AlliedSignal (now Honeywell) process for its representative process. The former is benzene and the latter is phenol. (2) The SNIA (Toluene route) and Toray (Photochemical Nitrosation route) processes are two different processes. Toluene process currently has only one set of equipment in China.
