How Is Adiponitrile Manufacturing?

Invista and Butachimie produce adiponitrile by reacting butadiene with hydrogen cyanide, a process developed by Invista's forerunner, DuPont. Ascend uses a Monsanto-invented electrochemical process that starts with acrylonitrile.

How is adiponitrile produced?

Adiponitrile is a large scale chemical intermediate used in the production of Nylon 6,6. It is primarily produced via two methods: the thermal hydrocyanation of butadiene and the electrochemical hydrodimerization of acrylonitrile.

How is nylon 6/6 produced industrially?

Nylon 6, 6 is produced from the step-growth polymerization of Adipic Acid and Hexamethylene diamine. This reaction occurs via the removal of water from a nylon salt that has a 1:1 ratio of Adipic Acid and Hexamethylene diamine. The polymerization can either occur continuously or in batches [1].
