催化劑以及制備該催化劑、其配體、乙酸和乙酐的方法

总结: The present invention is a kind of micro-porous spherical crosslinked copolymer ligand rhodium carbonylation of methanol synthesis catalyst. Wherein the copolymer of vinyl pyridine ligand, ethylene glycol diester formed crosslinked copolymer. Use of ligands N, O donor atoms with four rhodium carbonyl dihalogenodihydroxynaphthalene sodium tetraphenylborate in effect, the formation of Rh (I) square planar chelate-type cis-dicarbonyl positive ion activity center. Negative ions (BPh _{4 ) ^{- . In methanol carbonylation reaction, such catalysts under relatively low (<140 ℃) to the conversion of methanol to acetic acid and acetic anhydride, and the reaction system, CO _{2 generation amount is less than 0.005mol% .}}}
