Dipropylamine, also known as di-n-propylamine, is a flammable, highly toxic corrosive liquid that exists in nature in tobacco leaves and artificially discharged industrial waste.  It is a colorless and transparent liquid. There is an ammonia smell. Can form hydrates. Easily soluble in water, ethanol and ether. Form hydrate with water。

application
Di-n-propylamine can be used as a solvent and an intermediate in the production of pharmaceuticals, pesticides, dyes, mineral flotation agents, emulsifiers and fine chemicals.

Production method

The preparation method is to use propanol as raw material and obtain it through catalytic dehydrogenation, ammoniation, dehydration and hydrogenation. The reaction catalyst is Ni-Cu-Al2O3, the pressure is (39±1)kPa, the reactor temperature is (190±10)℃, the space velocity of propanol is 0.05~0.15h-1, and the raw material ratio is propanol. ∶Ammonia:Hydrogen=4:2:4, dipropylamine and tripropylamine are obtained at the same time, and dipropylamine can be obtained by fractionation。
