Abstract

TITLE: A PROCESS FOR PRODUCING ACETIC ACID BY REACTING METHANOL WITH CARBON MONOXIDE. IN A PROCESS FOR PRODUCING ACETIC ACID BY REACTING METHANOL WITH CARBON JMONOXIDE INA LIQUID REACTION MEDIUM COMPPRISING A CATALYTICALLY EFFECTIVE AMOUNT OF RHODIUM CATALYST; FROM ABOUT 0.1WT% TOLESS THAN 14 WT% OF WATER; ACETIC ACIDL A SALT SOLUBLE IN THE REACTION MEDIIUM AT THE REACTION REMPERATURE IN AN AMOUNT OPERATIVE TO MAINTAIN A CONCENTRATION OF I ONIC IODIDE IN THE RANGE OF FROM ABOUT 2 TO ABOUT 20 WT% EFFECTIVE AS A CATALYST STABILIZER AND CO-PROMOTER, METHYL IODIDIE; FROM ABOUT 0.5WT% TO ABOUT 30 WT% OF METHYL ACETATE, METHYL IIODIDE, AND SUBSEQUENTLY RECOVERING ACETIC ACID FROM THE RESULTING REACTION PRODUCT, THE IMPROVEMENT WHICH COMPRISES: REDUCING CONTAMINATION OF THE PRODUCT ACETIC ACID OF CARBONYL IMPURITIES BY MAINTAINING IN THE REACTION MEDIUM DURING THE COURSE OF THE REACTION LESS THAN ABOUT 4.5WT% OF METHYL IODIDE.
