Process Economics Program Report 210
Hetercyclic Nitrogen Compounds
Published: January 1993
This report contains preliminary process designs and cost estimates for the production of four heterocyclic nitrogen compounds:
- cyanuric acid.
Pyridine and 3-picoline are coproduced by reacting acetaldehyde, formaldehyde and ammonia in the vapor phase over a silica-alumina catalyst. 2-Picoline is manufactured from acrylonitrile and acetone in a separate plant section. Cyanuric acid is produced by the pyrolysis of urea. The report also discusses the industry status of each of the products, and the basic chemistry of the manufacturing processes.
