Abstract: The present invention is one kind of methanol oxo-synthesis rhodium catalyst with crosslinked porous microspherical polymer as ligand. The polymer is formed with vinyl pyridine and glycol acrylate and through crosslinking copolymerization. The N and O donor atom in the ligand and tetracarbonyl dirhodium dihalide, under the action of sodium tetraphenylborate, form square planar cis-bicarbonyl Rh(I) structure as positive active center. The negative ion is (BPh₄)-. During the methanol carbonylation, the catalyst can convert methanol into acetic acid and acetic anhydride at relatively low temperature and the CO₂producing amount in the reaction system is lower than 0.005 mol%.
