A solid catalyst comprising an effective amount of iridium and at least one second metal selected from gallium, zinc, indium and germanium associated with a solid support material is useful for vapor phase carbonylation to produce carboxylic acids and esters from alkyl alcohols, esters, ethers or ester-alcohol mixtures. The iridium and at least one second metal are deposited on a support material. In some embodiments of the invention, the catalyst is useful for vapor phase carbonylation.

Iridium catalysts for carbonylation

Carbonylation catalysts and methods for using them are disclosed. In some embodiments, the carbonylation catalyst includes the contact product of:

Carbonylation catalyst and process using same

Disclosed is a hydrocarboxylation process for the production of carboxylic acid from olefins wherein an olefin, water, a Group VIII metal hydrocarboxylation catalyst, an onium salt compound are combined in a reaction zone and contacted with carbon monoxide under hydrocarboxylation conditions of pressure and temperature The process does not require or utilize the addition of a hydrogen halide or an alkyl halide exogenous or extraneous to the hydrocarboxylation process.

Hydrocarboxylation process

Disclosed is a carbonylation process for the production of carboxylic acids, carboxylic acid esters and/or carboxylic acid anhydrides wherein a carbonylation feedstock compound selected from one or more organic oxygenates such as alcohols, ethers, and esters is contacted with carbon monoxide in the presence of a carbonylation catalyst and one or more onium compounds. The carbonylation process differs from known carbonylation processes in that a halide compound such as a hydrogen halide, typically hydrogen iodide, and/or alkyl halide, typically methyl iodide, extraneous or exogenous to the carbonylation process is not fed or supplied separately to the process.

Carbonylation process

The present invention provides chemical processes for the preparation of disaccharide and trisaccharide C to C fatty acid esters having a high alpha content. Yet still further, the invention provides materials prepared by the processes disclosed herein.
