PA-66 - 制法
单体制备(1)苯酚法 苯酚加氢生成环己醇，再用硝酸氧化制成己二酸。己二酸氨化脱水生成己二氰，再加氢生成己二胺。(2)环己烷氧化法 环己烷经空气氧化生成环己醇和环己酮的混合物，再用硝酸氧化生成己二酸（也有采用环己烷一步氧化生成己二酸的方法）。用于苯酚法相同的过程由己二酸制成己二胺。(3)丁二烯法 丁二烯氯化生成二氯丁烯，经氰化生成二氰基丁烯，再加氰生成己二氰。己二氰氧化生成己二胺。己二酸可通过前两种方法制成。(4)丙烯腈电解法 丙烯腈电解还原二聚生成己二腈，再加氢生成己二胺。(5)己二醇法 环己烷氧化生成环己醇和环己酮，经分离后，将环己醇脱氢制成环己酮，将它用guocusuan氧化生成己内酯，再氢化生成己二醇。己二醇经氨化生成己二胺。
缩聚 将等物质的量的比的己二酸与己二胺在乙醇中于60℃中和成尼龙66盐。尼龙66盐于280℃，1.76～1.96MPa压力下缩聚，即得到尼龙66树脂。亦可将己二酸与己二胺以等物质的量的比在水溶液中直接缩聚生成尼龙66树脂。
PA-66-Preparation method
Preparation of single system: (1) Phenol method: Phenol is hydrogenated to produce cyclohexanol, which is then oxidized with nitric acid to produce adipic acid. Adipic acid mak ammoniated and dehydrated to produce hexamethylene cyanide, which is then hydrogenated to produce hexamethylene diamine. (2) Cyclohexane oxidation metodu: Cyclohexane mak oxidized husi anin atu form a mixture ida ba cyclohexanol no cyclohexanone, no depois oxidized ho acid nitric atu prodús adipic acid (iha mós metodu ne ' ebé uza oxidation ida-step oxidation ba cyclohexane atu prodús sidade adipic). Prozesu ne'e hanesan uza ba metodu phenol, inklui produksaun asida adipic ba amin adipic (3) butadiene method generates dichlorobutene by chlorination of butadiene, which is then cyanated to form dicyanobutene, and then cyanide is added to form hexamethylene. Hexanediamine halo husi oksidataun hexamethylene cyanide Adipic acid bele halo husi metodu rua husi uluk. (4) Acrylonitrile electrolysis method: Acrylonitrile electrolysis reduces dimerization to produce adipic nitrile, which is then hydrogenated to produce adipic diamine. (5) Metodo cyclohexanol prodús cyclohexanol no cyclohexanone husi oxidation ba cyclohexane. Hafoin separasaun, cyclohexanol mak dehydrogenated atu prodús cyclohexanone, ne ' ebé mak oxidized ho acid peracetic atu prodús caprolactone, no depois hydrogenated atu prodús hexanediol. Hexanediol is ammoniated to form hexamethylene diamine.
