Abstract

Carbonylation of ethanol using IrCl3 · 3H2O as catalyst precursor with HI as a promoter is reported. The role of N- and P-containing ligands and solvents, and the influence of reaction conditions on the activity and selectivity is discussed. The average activity vs. HI concentration showed an unusual trend with a maximum. The water-gas shift reaction was found to be significant above 483 K and at higher concentrations of HI (»1.12 × 10-3 mol cm-3).
