Abstract

Controlled Surface Reactions (CSRs) based on the reactivity of adsorbed hydrogen towards tin alkyl compounds were used for the modification of a skeletal nickel catalyst. The modification of the skeletal nickel catalyst with tin was aimed to suppress the formation of isopropylalcohol in the reductive amination of acetone. The introduction of tin tetraalkyls into the catalyst resulted in an increase of the formation of diisopropylamine and slight decrease of the formation of alcohol. Upon using tin dibenzyl dichloride for the modification of the catalyst strong suppression of the selectivity towards isopropanol could be achieved. X-Ray diffraction revealed the presence of Al3Ni2 and AlNi alloys, metallic Ni, NiO, Al(OH)3 and AlO(OH) in the heat treated catalyst, the latter could be responsible for the enhanced selectivity towards the formation of secondary amine at 190-200°C.
