CARBOXYLIC ACID PRODUCTION BY CARBONYLATION OF AN ALCOHOL USING CO IN A LIQUID REACTION COMPOSITION COMPRISING RHODIUM CATALYST, ALKYL HALIDE, AND A PROMOTER

摘要

A process for the carbonylation of a C1 to C4 alkyl alcohol and/or a reactive derivative thereof by contacting a C1 to C4 alkyl alcohol and/or a reactive derivative thereof with carbon monoxide in a liquid reaction composition in a carbonylation reactor in the presence of (a) a rhodium catalyst, (b) an alkyl halide, and (c) as promoter, at least one of ruthenium and osmium.
