Verfahren zur Herstellung von Essigsäure und heterogener Katalysator dafür.

摘要

An improved Monsanto-type process for acetic acid preparation and a heterogeneous-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 DEG C 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.
