Aziridine is produced industrially from aminoethanol via two related routes.  The Nippon Shokubai process requires an oxide catalyst and high temperatures to effect the dehydration.  In the Wenker synthesis, the aminoethanol is converted to the sulfate ester, which undergoes base-induced sulfate elimination.  Older methods entailed amination of 1,2-dichloroethane and cyclization of 2-chloroethylamine.
Aziridine forms a wide variety of polymeric derivatives, known as polyethylenimines (PEI). These and related species are useful crosslinking agents and precursors for coatings.
