聚己内酰胺粉制备

1.单体己内酰胺的制备　有下面的5种合成方法。
苯酚法　由苯酚加氢生成环己醇，氧化脱氢生成环己酮，肟化生成环己肟，再经转位生成己内酰胺。

环氧己烷法　环己烷氧化生成环己醇和环己酮的混合物，环己醇分离后脱氢生成环己酮，再肟化生成环己酮肟，再经转位生成己内酰胺。
光亚硝化法　环己烷在光照下用氯化亚硝酰进行亚硝酰化反应生成环己酮肟盐酸盐，在硫酸中进行贝克曼重排生成己内酰胺。
甲苯法　由甲苯氧化制得苯甲酸，氢化生成环己甲酸，再用亚硝基硫酸和发烟硫酸进行亚硝基化反应即生成己内酰胺。
己内酯法　环己酮在醋酸或过氧化氢作用下生成己内酯，再于高温高压下氨化即得己内酰胺。

2.尼龙6树脂的制备　以己内酰胺为原料，在高温（220～260℃）及引发剂（水）存在下，首先制得氨基己酸，然后缩聚和加成反应同时进行而制得尼龙6树脂。反应式如下。
