IPDI Production from Isophorone and Chlorine
This report presents the economics of Isophorone Diisocyanate (IPDI) from isophorone and chlorine in the United States. In the process examined, isophorone is reacted with hydrogen cyanide, generating IPN. IPN obtained is then reacted with ammonia to form IPNI, which is hydrogenated with more ammonia to yield IPDA. Finally, IPDA reacts with phosgene to produce IPDI. The phosgene used is generated from chlorine and carbon monoxide.
IPDI Production from Isophorone and Urea
This study examines the economics of Isophorone Diisocyanate (IPDI) production from isophorone and urea in the United States. This process is a non-phosgene route. In the non-phosgene process, IPDA reacts with urea and butanol generating a carbamate intermediate. Then, the carbamate is thermally cracked producing IPDI.
