Product Application of Triethylenediamine CAS#280-57-9

Triethylenediamine is an important chemical raw material. It is used as a catalyst for polyurethane and also as an oil additive. It is used as a corrosion inhibitor in boiler water treatment, a catalyst for polyurethane foaming and polymerization, an accelerator for epoxy resin curing, and a catalyst for acrylonitrile, ethylene and ethylene oxide. It is a non-nucleophilic base, a reagent for splitting β-keto esters and geminal diesters and dehydrohalogenation reactions, and forms complexes with organic magnesium, lithium, and zinc compounds to increase activity and participate in many reactions.
