Octadecanenitrile → Octadecylamine

Participants

Reaction Steps

300 g of stearonitrile were fed into a 1 liter autoclave and then 3 g of Catalyst A, 12 g of water and 1 g of 48% sodium hydroxide were put thereinto. After purging with nitrogen gas, the reaction was carried out under the hydrogen pressure of 2.0 MpaG at the reaction temperature of 120° C. The reaction-finishing point was determined at the point where the hydrogen gas was no longer absorbed. The reaction system was aged further for 15 minutes. Absorption of hydrogen gas proceeded smoothly and the absorption was completed in 0.8 hour. After finish of the reaction and aging, the reaction product was taken out from the reactor and the catalyst was removed off. Then, the reaction product was distilled and purified under 0.27 kPa at 220° C. Stearylamine was obtained with yield of 94%.
