Mainly used as polyurethane foam (hard bubble, soft bubble) catalyst. It can be used directly or used with A-33. There are also initiators used in pesticide production (such as hexampyridine initiators), and cyanide-free plating additives. The product is strong alkaline, low toxicity, irritant, should wear protective equipment when using.
Triethylene diamine is an important chemical raw material, used as a catalyst for polyurethane, and also used as an oil additive. It is used as a corrosion inhibitor in boiler water treatment, as a catalyst for polyurethane foaming and polymerization, as an accelerator for epoxy resin curing,ethylene and alkylethylene oxides; As a non-nucleophilic base, it is a reagent for splitting β-ketoacetic acid and diacetal acid and dehalogenation reactions, forming complexes with organic magnesium, lithium, zinc compounds to increase activity and participate in many reactions.
