Nylon 6, 6 Production - Cost Analysis - Nylon 66 E12A

Book excerpt: This report presents a cost analysis of Nylon 6,6 production from adipic acid and hexamethylenediamine (HMDA). The process examined is a typical continuous polymerization process. In that process, adipic acid and HMDA are first reacted to form a nylon salt solution that is further fed to a polymerization section. Polymerization is carried out in multiple stages and the polymer melt formed is transferred to the finishing section.
