Title:
Carbonylation of lower alkyl alcohols and their derivatives using metals supported on carbonized polysulfonated divinylbenzene-styrene copolymers
Document Type and Number:
WIPO Patent Application WO2001077059
Kind Code:
A3
Abstract:
A method for producing esters, carboxylic acids and mixtures thereof includes contacting, under carbonylation conditions, lower alkyl alcohols, ethers, lower alkyl alcohol derivatives and mixtures thereof and carbon monoxide with a catalyst having a catalytically effective amount a metal selected from iron, cobalt, nickel, ruthenium, rhodium, palladium, osmium, iridium, platinum, tin and mixtures thereof associated with a carbonized polysulfonated divinylbenzene-styrene copolymer matrix. In a preferred aspect of the invention the method is called out under vapor-phase conditions.
