Process for acetic acid preparation and heterogeneous catalyst for same

Abstract From the Canadian patent

of the Invention, An improved Monsanto-type process for acetic acid preparation and a heterogoneous-supported catalyst for accomplishing the same, comprising reacting methanol with carbon monoxide under pressure of about 65-80 Bar and temperature of about 170-200° in the presence of methyl iodide and a catalyst comprising an insoluble polymer having pendant free base. N-oxide or quaternized pyridine groups supporting a rhodium species loaded to less than about 10 weight percent (expressed as metal) of the polymer component.
