Abstract:
This invention relates to a catalyst used in a carbonylation of methanol using carbon monoxide to acetic acid, and more particularly to a heterogeneous catalyst represented by Rh/WxC (where x is an integer of 1 or 2) in which a complex of a rhodium compound and 3-benzoylpyridine is fixed on a support of tungsten carbide.
