What to read after IPDI Production from Isophorone and Chlorine - Cost Analysis - IPDI E11A?

This report presents a cost analysis of Isophorone Diisocyanate (IPDI) production from isophorone and chlorine.

The process examined is a typical phosgenation process.

In this process, isophorone diamine (IPDA) intermediate is initially obtained from isophorone. Then, IPDA reacts with phosgene to produce IPDI. The phosgene used is generated from chlorine and carbon monoxide in an on-site unit. Hydrogen chloride (HCl) is generated as by-product.
