On May 5, the nylon 66 new material project of Sinochem International Yangnong Group Ruitai Company, a subsidiary of Sinochem Group, located in Sinochem Zhongwei Circular Economy Industrial Park, was successfully started and produced qualified products
.
Sinochem announced that the nylon 66 new material project took three years of research and development and one year of construction.
Since the start of the ammoniation plant on April 20, after half a month of commissioning and operation, the whole process of the project has been successfully completed.
The device drives successfully once

The main raw materials of nylon 66 are adipic acid and hexamethylene diamine
.
Among them, adiponitrile, the key synthetic raw material of hexamethylenediamine, belongs to China's "stuck neck" product.
The domestic production capacity is slow to develop due to the "controlled by others" of production technology, and the price remains high, which has become a major bottleneck restricting the development of nylon 66 industry

.
After years of research and development, Sinochem International has independently developed an innovative production process of hexamethylenediamine, and has formed the first domestic set of "catalyst preparation - hexamethylenediamine synthesis by introducing and re-innovating the aqueous solution salt-forming continuous polymerization method nylon 66 process technology.

.
This innovative production process uses bulk chemicals as raw materials to directly prepare hexamethylene diamine through a two-step reaction, cleverly bypassing the long-term monopoly of multinational companies on the technology and supply of adiponitrile, the key raw material of nylon 66
.
Compared with the traditional production process of hexamethylenediamine, it also has the advantages of easy availability of raw materials, less investment, no highly toxic chemicals such as hydrocyanic acid, and high level of safety and environmental protection

The nylon 66 project was established in 2020 and started construction in April 2021, and was included in the key projects of the Ningxia Hui Autonomous Region in 2021
