VAPOR PHASE CARBONYLATION PROCESS USING PROMOTED IRIDIUM CATALYST |
摘要 |
A method for producing esters and carboxylic acids from lower alkyl alcohols, ethers, esters and ester-alcohol reactant mixtures and includes the step of contacting a vaporous mixture of the reactants, carbon monoxide and a halide with a supported catalyst under vapor-phase carbonylation conditions. The catalyst includes iridium and a second metal selected from group 4 (titanium, zirconium, hafnium) metals of the periodic table of elements. Desirably, the iridium and secondary metal are deposited on activated carbon as a support material. In a preferred aspect of the invention, the vapor phase carbonylation process is useful for preparing acetic acid, methyl acetate or a mixture thereof.
