Appl. No.:

8/596488

Inventors:

Michael James Baker - Hull, GB2

International Classification:

C07C 6736
C07C 5112

US Classification:

560232

Abstract:

In a process for the liquid phase carbonylation of an alkyl alcohol such as methanol, and/or a reactive derivative thereof to produce the corresponding carboxylic acid and/or ester, in the presence of an iridium catalyst, an alkyl halide and water, the reaction is promoted by the presence of at least one promoter selected from cadmium, mercury, zinc, gallium, indium and tungsten, optionally with a co-promoter selected from ruthenium, osmium and rhenium.

C07C 5312
C07C 5112

US Classification:

562519

Abstract:

A process for the production of a carboxylic acid by carbonylation of an alkyl alcohol or its reactive derivative comprises contacting the reactant with carbon monoxide in a liquid reaction composition comprising: (a) an iridium catalyst or rhodium catalyst, (b) alkyl halide, (c) at least a finite concentration of water and (d) rhenium as promoter.
