Download or read book Hexamethylene Diisocyanate Production - Cost Analysis - HDI E12A written by Intratec and published by Intratec. This book was released on 2019-09-17 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a cost analysis of Hexamethylene Diisocyanate (HDI) production from hexamethylene diamine (HMDA) and urea. The process examined is a non-phosgene technology similar to the process developed by BASF. In this process, HMDA reacts with urea and butanol generating a carbamate intermediate. Then, the carbamate is thermally cracked producing HDI. This report was developed based essentially on the following reference(s): (1) US Patent 5386053, issued to BASF in 1995 (2) US Patent 6410778, issued to BASF in 2002 Keywords: Hexamethylene Diisocyanate, HDI, Hexamethylene Diamine, HMDA, BASF, Non-Phosgene, Urea-Based Process
