Azepan-2-One Production from Butadiene
Azepan-2-One Production Cost Breakup from Butadiene
This report presents a detailed cost analysis of caprolactam (azepan-2-one) production via hydrocyanation of butadiene.
Last Updated: January, 2025
This report presents a detailed cost analysis of caprolactam production from butadiene. In this process, the hydrocyanation of butadiene takes place as the first step, where butadiene reacts with hydrogen cyanide in the presence of a nickel catalyst to form adiponitrile. This adiponitrile is then partially hydrogenated over a catalyst, resulting in a mixture of hexamethylenediamine (HMDA) and some unreacted adiponitrile. Following this, the mixture undergoes distillation to separate the HMDA from the adiponitrile. The adiponitrile that remains is then hydrolyzed using water and an acid catalyst to produce adipic acid. Finally, the adipic acid is dehydrated and cyclized to create caprolactam, which is a precursor for manufacturing Nylon 6.
