A process for the production of acetic acid by carbonylation catalyzed by Iridium

摘要

A process for the production of acetic acid which comprises (1) continuously feed Methanol Reagent and / or a derivative thereof and MONOXIDE emissionsa a carbonylation reactor containing aLiquid composition comprising uncatalizador carbonylation reaction of Iridium, Methyl cocatalizador deyoduro, a Finite concentration of water, acetic acid,Methyl acetate and optionally at least one Promoter; (2) carbonilar Methanol and / oderivado reactive with carbon monoxide in the composition of reaction LiquidTo produce acetic acid; and (3) to recover acu00e9ticode acid Composition of reaction Liquid is continuously maintained, where (a) the composition of reaction LiquidWater in a concentration of not more than a4,5% by weight, and (b) in a reactor, the partial pressure of carbon monoxide in the range from 0 to 7.5 bar.Officers of the acetic acid is in the manufacture of Cellulose acetate Plastic and acetate, acetic anhydride, Ester Solvents, metal Acetates; put it, the manufacture of Pigments.In the preparation of Paris green as insecticide; and in the production of acetamide, aspirin and Other Drugs.It is also of Great Utility as a Solvent in Organic reactions; Industry of Latex, Rubber Stopper; as in Photography, like acid, General PurposeThe manufacture of Chemicals and Textile Processing.The figure is a graph of the speed dereaccion versus percentage of water 30% Methyl deacetato, effect of partial pressure of co for reactions catalyzed with go without Promoting.It demonstrates that a CONCENTRACIONDE 30% Methyl acetate carbonylation reaction for the composition not promoted, as it reduces the total pressure, and
