In the synthesis of acetic acid by the carbonylation of methanol catalyzed by RhCl<SUB>3</SUB>·3H<SUB>2</SUB>O or Rh<SUB>2</SUB>Cl<SUB>2</SUB>(CO)<SUB>4</SUB>in the presence of methyl iodide, it was found that ketone solvents, such as acetophenone and benzophenone, keep both the catalytic activity and selectivity high, even at an elevated temperature. The kinetic results in acetophenone are in agreement with the mechanism proposed by Paulik and Roth. The effect of the ketone solvent was discussed by taking account of the competitive oxidative addition of hydrogen iodide with methyl iodide.
