Tetramethyl-1,3-diaminopropane Usage And Synthesis

Description	Tetramethyl-1,3-diaminopropane can be made by methylation of 1,3-diaminopropane with formaldehyde or from dimethylaminopropionitrile and dimethylamine and is an intermediate for corrosion inhibitors, textile auxiliaries, flotation agents, and emulgators. It is also employed as a catalyst for polyurethanes and as a hardener for epoxy resins.
Chemical Properties	colourless liquid
General Description	N,N,N′,N′-Tetramethyl-1,3-propanediamine is an acyclic tertiary amine. It shows the ability to absorb CO₂when dissolved in aqueous solution. N,N,N′,N′-Tetramethyl-1,3-propanediamine (TMPDA) may be used: As a catalyst for the Baylis-Hillman reaction of cycloalkenones. In the preparation of homodimeric asymmetric monomethine cyanine dyes during the bisquaternization process. As a ligand (L) for the preparation of dinuclear μ-carbonato-dicopper(II) species.
Flammability and Explosibility	Flammable
