Introduction
Pentamethyldiethylenetriamine is a colorless to light yellow clear liquid, easily soluble in water. It is a highly active catalyst for polyurethane reaction. It mainly catalyzes the foaming reaction, and is also used to balance the overall foaming Chemicalbook and coagulation. Adhesive reaction, widely used in various polyurethane rigid foams, including polyisocyanurate sheet rigid foams. The production methods of pentamethyldiethylenetriamine include formaldehyde formic acid method and formaldehyde hydrogenation method.
Applications
Ligands for neopentyllithium complexation were studied by NMR, and the effect of ligands on CO2 interacting with α,ω-diynes was studied. N,N,N',N'',N''-pentamethyldiethylenetriamine catalyst is a highly active tertiary amine catalyst. Due to its unique steric shielding interaction of amino nitrogen, its basic The properties can more effectively catalyze the reaction between water Chemicalbook and isocyanate, so N,N,N',N'',N''-pentamethyldiethylenetriamine is an excellent rigid foam and The foaming catalyst of flexible foam is often shared with DMCHA, etc. N,N,N',N'',N''-pentamethyldiethylenetriamine is also used to balance the overall foaming and gelling reactions.
