Carbonylation of methyl acetate into acetic anhydride on Rh and Ir catalysts exchanged in NaY zeolithes
Written by sctunisie no commentsThe reduction of Rh (III) and In (III) by means of carbon monoxide at a moderate temperature leads to the formation of complexes of definite dicarbonyles of rhodium or iridium. The oxidation of halogeno methane by these complexes leads to an M-R bond which reacts with carbon monoxide to produce an acyl bond. The complex transforms through a reducing elimination of the acetyl halogen in the presence of methyl acetate, to form acetic anhydride.
