Synthesis of 3-aminopropyltriethoxysilane via catalytic hydrogenation of 2-cyanoethyltriethoxysilane

Activation of the industrial cobalt catalyst consisting of 24.8 wt% cobat, 0.3 wt% thorum and 1.2 wt% aluminium tin the form of the oxides supported o n silica) modified by potassium corbonate makes it suitable for use in a ve ry effective hydrogenation of 2-cyanoethyltriethoxysilane leading, under op timum conditions (150 degrees C, 5.1 MPa H-2), to a quantitative synthesis of 3-aminopropyltriethoxysilane, the commonest silane coupling agent with n itrogen functionality.
