Secondary isopropyl amines derived from oxyalkylene triamines

摘要

Secondary isopropylamine terminated oxyethylene and/or oxypropylene diamines or triamines are prepared by reacting an oxyethylene and/or oxypropylene primary diamine or triamine with acetone in the presence of a hydrogenation catalyst and hydrogen. The secondary isopropylamine terminated oxyethylene and/or oxypropylene derivatives are useful as curing agents for epoxy resins.
