Abstract
The carbonylation of ethanol using NiCl2 · 6H2O/isoquinoline catalyst system and aqueous HI as a promoter has been investigated. Effect of catalyst, ethanol and HI concentration, temperature, partial pressures of CO and H2, N- or P-containing ligands and co-catalysts on the activity and selectivity has been studied. The Ni catalysts were found to be active only in the presence of N- or P-containing ligands. LiI and NaI were found to further enhance the catalytic activity without affecting the selectivity. Activity of Ni-isoquinoline-HI catalyst was found to be constant even after 4 recycles indicating high stability.
