Yield:3218-02-8 91%

Reaction Conditions:

with hydrogen in ethanol at 88; under 37503.8 Torr; for 0.5 h;

Steps:

1 Amines Preparation Examples
In the 1L hydrogenation kettle, add 100 g of cyclohexanecarbonitrile and 3 g of Raney-Ni, 400 mL of ethanol, and continuously charged with H2, so that the pressure of the system during the reaction was always maintained at 5 MPa. After reaction at a reaction temperature of 88 ° C for 0.5 h, then the temperature was lowered. When the temperature in the reaction vessel was lowered to room temperature, the gas was vented, and c cyclohexanemethylamine (purity: 99% or more) was obtained by filtration and recrystallization in a yield of 91 wt%.
