Title: VAPOR-PHASE CARBONYLATION OF LOWER ALIPHATIC ALCOHOLS USING TIN PROMOTED IRIDIUM CATALYST
Abstract:
A vapor-phase carbonylation method for producing esters and carboxylic acids from reactants comprising lower alkyl alcohols, lower alkyl alcohol generating compounds, and mixtures thereof. The method includes contacting the reactants and carbon monoxide in a ccarbonylation zone of a carbonylation reactor under vapor-phase conditions with a catalyst having a catalytically effective amount of iridium and tin associated with a solide carrier material.
