        一项 innovation 架起两 strip/profile product 链

         caprolactam made hexamethylenediamine process front due to tool has property, degree development outlook/prospects 不明朗. its main/primary raw materials caprolactam production capacity growth price lower slip, process property positive in 显现. future if can breakthrough process key/critical bottle 颈, caprolactam — nylon full industry chain, formed nylon 6 and nylon 66 “ di 龙驱动” large type new material industry 集群, that process future outlook/prospects value 期待.

        经济 property 逐步显现

         caprolactam made hexamethylenediamine process is caprolactam and in catalytic agent function lower, formed 氨基己腈, rear for 氨基己腈 add hydrogen to hexamethylenediamine. process Toray 于1965 year achieve industrial 化, main/primary used for nylon 6 factory recycling caprolactam product or waste nylon and other waste raw materials recycled utilizing. therefore, process 一直不 tool has property, inner relatively less.

         as is process main/primary raw materials, caprolactam production capacity and output/production volume 自2010以 稳步 growth, new increase and expand increase caprolactam project increase more, year caprolactam production capacity more large expand 张之势, already new increase year production capacity 123 10,000 tons. year year 底, caprolactam year production capacity will 达477 10,000 tons, 面临 剩危 machine, market price 也随之逐步 lower slip.

         and butadiene hydrogen method made hexamethylenediamine versus ratio, liquid caprolactam 均价13800元(吨价, lower 同), caprolactam made hexamethylenediamine process raw materials cost is 15000元 left right; butadiene price is 8000 more 元, butadiene hydrogen method raw materials cost in 11000元 left right. although currently in cost upper caprolactam made hexamethylenediamine process tool advantages, future year caprolactam toward 剩, raw materials price decline rear, process property 会逐步 improve/increase. but also caprolactam made hexamethylenediamine process investment ratio butadiene hydrogen method need low, production is 5 10,000 tons / year caprolactam made hexamethylenediamine plant/unit investment 保守估计不会 ultra- 4 100 million yuan, safety property and environmental protection property excellent butadiene hydrogen method.

         in addition, butadiene hydrogen method is 英威达, rise and other less outer company 掌握, 我国尚未 achieve independent production. in caprolactam production capacity will 面临 剩 形势 lower, market upper caprolactam made hexamethylenediamine, technology relatively low, technology safety can property relatively high, can separation substitute/replace butadiene hydrogen method.

        氨化脱 water reaction is key/critical

         caprolactam made hexamethylenediamine 需经历 below/following reaction process: 第一步 is caprolactam and gas 发生氨化开 ring reaction formed 6-氨基己酰 amine;第二步 is 6-氨基己酰 amine water remove oxygen reaction, formed 6-氨基己腈;第三步 is 6-氨基己腈 and hydrogen gas add hydrogen reaction obtain hexamethylenediamine. versus relatively 而言, 第三步 reaction technology relatively formed 熟, and industrial 己二腈 add hydrogen made hexamethylenediamine similar, can using/adopting skeleton/framework 镍, iron —镍 or 镍—铬 catalytic agent in hydrogen oxidation solvent liquid in 进行, reaction temperature degree 75℃, pressure 3MPa, hexamethylenediamine selection property 达99%. as process target/goal material rate high, safety property and can property relatively strong/high.

        而第一步 and 第二步 reaction is 一 连续 氨化脱 water process, in reaction device in 进行, currently is technology core. water reaction can 逆, add amount gas, and troubleshooting formed water, improve/increase 6-氨基己腈收 rate, generally selection acid salt as is main/primary catalytic agent. according to caprolactam reaction can separation is gas versus method and liquid versus method types, liquid versus method reaction conditions temperature and, catalytic agent and product separation 离繁琐, can consumption high. gas versus method made simple, in material and catalytic agent separation issues, using/adopting catalytic agent made simple, difficulty/challenge in catalytic agent stability property 尚未经 industrial 化验证. gas versus method reaction temperature degree 达350℃, catalytic agent need maintain active property, selection property, heat stabilized property and other property can and structure 不变, in design upper need improve/increase active property structure heat stabilized property.

         caprolactam 氨化脱 water process reaction mechanism comparison complex, 包含C-N键 fracture and formed process. caprolactam need 打开C-N键, ring separation ring formed separation 子, meanwhile ketone upper carbon 原子键 combined 氨基生 formed 链式酰 amine separation 子, rear 进一步发生脱 water reaction oxygen 原子脱掉生 formed separation 子, upper 述每一步 reaction effect/influence 6-氨基己腈 combined formed efficiency. therefore, caprolactam made hexamethylenediamine technology industry 化, need from reaction mechanism, process upper in-depth research, its need high catalytic agent made and its in 试, industrial 化验证, 以此确定 gas versus method and liquid versus method more has comprehensive advantages.

        一体化 will add separation 化

         currently, new start production caprolactam production capacity basic upper achieve ring ketone sleeve/set and raw materials to, cost large reduce. caprolactam basic used for production nylon 6, caprolactam lower 游 切 sheet/slice, filament production enterprise in toward upper expand 张. overall 看, upstream and downstream 一体化进程 in accelerated, ring ketone — caprolactam — polymerization —纺 filament 一体化 进程也 in add fast. its in, group already rate 先打通 ring ketone — caprolactam — polymerization —纺 filament —织造—染整 完整 industry chain. filament high speed expand will again upper 游, caprolactam — nylon 6 industry will structure property production capacity and competition add 剧.

         future year, has sleeve/set lower nylon 6 polymerization caprolactam production enterprise, especially is 2014 year rear large separation new increase production capacity 山西, 河南, and other chemical industry enterprise, versus ratio 一体化 enterprise in can force, comprehensive competition force relatively low. currently 看, caprolactam — nylon 一体化 already is development trend, caprolactam made hexamethylenediamine industry in 眉睫, caprolactam made hexamethylenediamine can from caprolactam — nylon 6 polymerization 一体化, upper toward caprolactam — nylon 66 polymerization 差异化一体化 new 征途.
