Abstract
A PROCESS TO REDUCE CARBONYL IMPURITIES IN A CARBONYLATION REACTION FOR THE PRODUCTION OF ACETIC ACID IS DESCRIBED. THE METHYL IODIDE RECYCLE STREAM WHICH IS DIRECTED TO A CARBONYLATION REACTOR FOR CARBONYLATING METHANOL OR METHYL ACETATE TO ACETIC ACID IS TREATED TO REMOVE CARBONYL IMPURITIES BY REACTING THE METHYL IODIDE STREAM FORMED IN THE REACTION WITH AN AQUEOUS AMINO COMPOUND WHICH REACTS WITH THE CARBONYLS TO FORM WATER SOLUBLE NITROGENOUS DERIVATIVES, SEPARATING AN ORGANIC METHYL IODIDE PHASE FROM AN AQUEOUS DERIVATIVE PHASE AND DISTILLING THE METHYL IODIDE PHASE TO REMOVE HEAVIER IMPURITIES. THE TREATMENT OF THE METHYL IODIDE RECYCLE STREAM TO THE CARBONYLATION REACTOR HAS BEEN FOUND TO GREATLY REDUCE THE CARBONYLS PRESENT IN THE ACETIC ACID PRODUCT. THE FORMATION OF NITRILE FROM THE NITROGENOUS DERIVATIVE DURING DISTILLATION MAY BE MINIMIZED BY ADDING WATER TO THE SYSTEM. (FIG 1)
