Conclusions

  1. 1.

    Promotion of 0.1% RhNaX catalysts with Group VI–VIII metal oxides increases their activity and selectivity for methyl acetate synthesis from methanol and CO.

     
  2. 2.

    Methyl acetate is formed with 92–100% selectivity at methanol conversions of >90% when the reaction is carried out at 210–240‡C and atmospheric pressure in the presence of catalysts promoted with Fe, Cu, and Mn oxides.

     
  3. 3.

    The reaction is zero order with respect to CO and CH3OH and first order with respect to CH3I, without which carbonylation does not take place.
