Abstract
Abstract This invention relates to multiphase catalysts, the preparation of the said catalysts, and catalytic processes employing such catalysts. The multiphase catalysts are comprised of a porous solid carrier upon which a liquid-phase catalyst is disposed. The liquid-phase catalyst includes liquid compounds which have catalytic activity, and also dissolved and dispersed solutes in a solvent. The multiphase catalysts are prepared by absorbing the liquid phase on the porous solid carrier, and may also have the liquid phase dissolved in a low boiling solvent which is later removed. The latter procedure provides intimate dispersion. The catalytic processes employing the multiphase catalysts include hydroformylation, isomerization, oxidation, carbonyl conversion and carbonylation reactions.
