The technology industrialization of nylon 12 industry chain was successful

On October 18, Wanhua Chemical Group Co.
, Ltd.
's 40,000 tons/year polyamide 12 (nylon 12) industrial chain equipment successfully produced high-quality products
.
This marks a major breakthrough in the industrialization technology of China's nylon 12 industry chain, and also means that Wanhua Chemical has become the second enterprise
in the world with the core technology and large-scale manufacturing capacity of nylon 12 industry chain manufacturing.

Wanhua Chemical's 40,000 tons/year nylon 12 project began preparations in 2012; In 2013, the pilot project was officially launched
.
Due to the complex process of the whole industry chain of the nylon 12 project, in order to accelerate the R&D process, Wanhua Chemical established a number of parallel R&D teams according to the reaction characteristics of the project, and each reaction unit carried out research at the same time, and then finally finalized a technical route with a yield better than the current foreign industrialization scheme based on the advantages of the Wanhua industrial chain, and gradually solved the engineering amplification problem of key processes and core equipment, realizing the revolutionary innovation
of nylon 12 technology.

In January 2019, the appraisal of the results organized by the China Petroleum and Chemical Industry Federation concluded that Wanhua nylon 12 technology had reached the international leading level, and the participating experts unanimously recommended to accelerate the implementation of industrialization; At the end of 2019, the project was approved by the EIA; Construction will start in full on April 15, 2020; From June 2022, each process will successively produce qualified products; On October 18, the last process of the industrial chain, nylon 12, successfully produced qualified products
.

From the basic synthesis research in the laboratory to the final development of a complete set of nylon 12 industry chain industrialization technology, Wanhua Chemical has been sharpening a sword for 12 years to provide strong support
for the development of high-end materials industry.
Wanhua Chemical said that this technological breakthrough has further enriched the series product system of fragrances and engineering plastics, providing more high-quality and stable products and solutions
for diversified industries.

Nylon 12 resin and its modified materials are bringing diversified choices
to advanced manufacturing fields such as additive manufacturing, new energy vehicles, oil and gas industry, and submarine cables due to their extremely low density, low-temperature toughness, impact resistance, and chemical resistance.

In the 70s of the 20th century, nylon 12 was first industrialized in
Marl by Degussa GmbH, the predecessor of Evonik Industries.
Subsequently, Swiss EMS, France's Arkema and Japan's Ube Industries (UBE) also announced the news of industrial production, and the four major manufacturers have mastered the production technology of nylon 12 for nearly half a century
.
Due to the long process route and high technical difficulty of the whole industry chain of nylon 12, it has been monopolized by foreign enterprises for a long time, resulting in all domestic nylon 12 materials relying on imports, and the downstream development is restricted
