Dimethylaminopropylamine (DMAPA), as an important organic chemical raw material, has a wide range of applications.

Dimethylaminopropylamine, referred to as DMAPA, is an organic raw material intermediate with the chemical formula C5H14N2. It appears as a transparent liquid, is flammable, and is soluble in water and organic solvents. At present, the mainstream production process of dimethylaminopropylamine is to use dimethylaminopropionitrile as raw material and prepare dimethylaminopropylamine through Ni-Al catalyst catalysis, hydrogenation, filtration, distillation and other links.
Dimethylaminopropylamine is an important organic chemical raw material that can be widely used in cosmetic raw materials, dyes, ion exchange resins, oils, fungicides, cyanide-free galvanizing additives, fiber and leather treatment agents, epoxy resin curing agents, daily necessities, Polyurethane foam catalysts and other fields.
