Web2 days ago · Ethylene itself is produced by steam or catalytic cracking 3 —both very energy-consuming processes—and is then transformed via two separate routes into ethanolamines and ethylene polyamines. For the production of ethanolamines, ethylene is transformed into ethylene oxide (EO) by direct partial catalytic oxidation. 4 Reacting …
