Title:
酢酸の製造用イリジウム触媒カルボニル化方法
Document Type and Number:
Japanese Patent JP4017723
Kind Code:
B2
Abstract:
A process for the production of acetic acid comprises (1) continuously feeding methanol and/or a reactive derivative thereof and carbon monoxide to a carbonylation reactor containing a liquid reaction composition comprising an iridium carbonylation catalyst, methyl iodide co-catalyst, a finite concentration of water, acetic acid, methyl acetate and, optionally at least one promoter, (2) carbonylating the methanol and/or reactive derivative thereof with the carbon monoxide in the liquid reaction composition to produce acetic acid; and (3) recovering acetic acid from the liquid reaction composition, there being continuously maintained (a) in the liquid reaction composition water at a concentration of no greater than 4.5% by weight, and (b) in the reactor a carbon monoxide partial pressure in the range from greater than 0 to 7.5 bar.
