In order to further optimize the product structure, extend the industrial chain and enhance the market competitiveness, Nanjing Chengzhi Clean Energy Co.
, Ltd.
(hereinafter referred to as "Nanjing Chengzhi") and the Institute of Process Engineering of the Chinese Academy of Sciences (hereinafter referred to as the "Institute of Processes of the Chinese Academy of Sciences") will independently develop For the new coal-based adiponitrile technology, the two parties have recently signed a technology research and development agreement, and it is planned to build a 3,000-ton/year project demonstration plant in advance.
Demonstration device

Adiponitrile is mainly used to prepare hexamethylene diamine, the intermediate of nylon 66.
Because of its high technical barriers and investment thresholds, its products and production technology are currently monopolized by foreign companies, resulting in China's "adiponitrile-hexanediamine-nylon".
The 66" industrial chain structure is seriously unbalanced

Adiponitrile is mainly used to prepare hexamethylene diamine, the intermediate of nylon 66.

Compared with the industrialized butadiene hydrocyanation method and acrylonitrile electrolytic dimerization method, the independently developed coal-based adiponitrile technology has relatively simple process, few reaction steps, low energy consumption, and does not involve highly toxic Chemicals are greener, safer and more cost-effective; at the same time, coal-based, echoing the reality of China's natural resource endowment, is more conducive to the safety of the relevant industrial chain and the clean utilization of coal

The coal-based adiponitrile technology is a brand-new process independently developed by the Institute of Processes of the Chinese Academy of Sciences.
It has applied for a number of patents and has a good industrialization prospect
