Estimating the term…
This invention relates in part to a processes and catalysts for the conversion of a feedstock comprising carbon monoxide and hydrogen to a product stream comprising at least one of an ester, acid, acid anhydride and mixtures thereof. This invention also relates in part to processes and catalysts for converting an alcohol, ether and/or ether alcohol feedstock to oxygenated products, e.g., esters, acids, acid anhydrides and mixtures thereof. The processes and catalysts are especially suitable for the production of acetic acid and methyl acetate from a synthesis gas feedstock or from an alcohol, ether or ether alcohol feedstock.
A solid catalyst for the carbonylation of a feedstock comprising at least one of an alcohol, ether, ether alcohol and mixtures thereof to a product stream comprising at least one of an ester, acid, acid anhydride and mixtures thereof, by reaction thereof in the vapor state, said catalyst comprising a solid super acid impregnated with from about 0.001 to about 10 weight percent of a Group 7, 8, 9, 10 or 11 metal or mixtures thereof.
