Mono-isopropylamine made from acetone or - isopropylalcohol using modified raney ni cat

摘要

Catalyst is made by treating Ni/Al alloy with alkaline solution. A solution of a salt of an alkaline earth metal (pref. MgCl2) is added to the catalyst after decanting so that an alkaline earth metal hydroxide is formed in situ on the surface of the catalyst when it is dried. To carry out the reaction the feedstock, an amide forming agent (pref. NH3), and a gas which contains at least 50% by vol. H2 (pref. synthesis gas) in ratio 1:2 to 4:8 to 20 are passed over the catalyst. Suitable reaction conditions are 0.1 to 3.0 (pref. 0.6 to 2.0) 1/1/h at 120 degrees C - 200 degrees C and 36 to 70 atmos heres. The reaction is particularly selective, gives high yields, and the catalyst has a long life.
