Technology from R&D to industrial application is often not a continuous process. Many technologies are interrupted in the R&D-industrialization process because of lack of economy and technology mismatch. Once the external conditions are mature, some technologies will revitalize.
At present, China has become a major producer of adipic acid and caprolactam in the world. The production capacity of adipic acid and caprolactam has been oversupplied. The industry is showing overcapacity. In the coming years, acrylonitrile will still have about 1300000 tons of new capacity to market. It is estimated that by 2020, the total production capacity of acrylonitrile in China will exceed 3 million 500 thousand tons / year, and China will surpass the United States as the world. The largest acrylonitrile producer, the vitality of technology has promoted the revival of adipic acid ammoniation and dehydration process, caprolactam process, acrylonitrile electrolytic dimerization process adiponitrile process.
China's national conditions have determined the future butadiene cyanidation process, adipic acid ammoniation dehydration method, caprolactam method, acrylonitrile electrolysis two polymerization process and so on. It has advantages of raw materials, enterprises with multiple products chain, comprehensive utilization of public works, comprehensive utilization of environmental protection facilities and comprehensive utilization of other auxiliary facilities, which can give full play to the comprehensive advantages of enterprises and determine these industries. Each artistic route has its own applicability. In October 10th, at the international forum of 2019 nylon monomer technology and market and the first two eye technology and market forum, the technical applicability and economy of butadiene cyanide hydrogenation, ammoniation and dehydration of adipic acid, caprolactam method and acrylonitrile electrolysis two polymerization technology were interpreted. The empty window period and strategic layout of Long66 industry are excellent.
In October 10th, the 2019 International Forum on nylon monomer technology and market held in Weihai and the first two eye technology and market forums will be attended by more than 70 leading companies and industry leaders from Yang Nong group, Kaisai biology, Shandong Hua Lu Heng Sheng, Henan gorge light polymer materials, Shandong Fuhai, Sinochem and Zhejiang Gamma. There are many enterprises and senior managers in the conference.

In the next five years, China will become the largest nylon Market in the world, and the nylon industry will be favored by industry and capital. However, various nylon monomer production technologies have restricted the development of nylon materials. At present, enterprises and research institutes in many provinces and municipalities such as, ",", ",", ",", ",", "and" have corrected the localization of adiponectin production technology, and the technology routes have been diversified. At the same time, the industrialization of nylon 5X and nylon 12 monomer production and polymerization is accelerating.
