    3-dimethylaminopropylamine (3-dimethylaminopropylamine) is also known as N,N-dimethylaminopropylamine, with a molecular formula of C 5 H 14 N 2 , a molecular weight of 88.
    17, and a structural formula of


    Product performance

    Appearance is a colorless and transparent liquid; this product is highly toxic and strongly irritating to the skin; it is alkaline and can react with acid to generate corresponding salts; relative density d 4 30 0.
    8100, boiling point 123°C, freezing point -70°C, lower than the freezing point It forms a glass body with a refractive index n D 25 1.
    4328; it is soluble in water and most organic solvents

    Production principle

    Acrylonitrile reacts with dimethylamine to produce dimethylaminopropionitrile

    The dimethylaminopropionitrile is hydrogenated with methanol as a solvent and Ni ( supported on Al 2 O 3 ) as a catalyst to obtain dimethylaminopropylamine


    Process flow


    Technical formula (kg/t)


    Main equipment

    Reactor (addition), fractionation tower, high pressure reactor (hydrogenation), filter, fractionation tower, storage tank

    Production process

    Add acrylonitrile to the kettle, stir, and pass a cooling medium in the jacket to cool the material below room temperature

    While stirring, add dimethylamine (40% concentration) dropwise

    The hydrogenation reaction uses methanol as the solvent

    The 3-dimethylaminopropionitrile prepared above was dissolved in an appropriate amount of methanol, put into the autoclave, and Ni-A1 catalyst (solid particles) was added

    Product use

    This product is used as a curing agent for epoxy resin, a brightener for non-cyanide electroplating, and it is also used for organic synthesis, synthetic dyes and the manufacture of ion exchange resins

    Safety measures

    (1) This product is highly toxic, and the raw material dimethylaminopropionitrile is toxic and has a strong irritation to the skin

    Production equipment should be sealed to prevent running, leaking, and leaking

    (2) Packed in iron drums, stored in a cool and ventilated place, away from fire

    Store and transport in accordance with toxic and flammable chemicals regulations
