Abstract
A process for the direct carbonylation of saturated hydrocarbons has been developed. The process involves contacting the saturated hydrocarbons, which contain at least one primary, secondary or tertiary carbon atom, with carbon monoxide in the presence of a solid strong acid catalyst to produce an oxygenated saturated hydrocarbon. In a specific embodiment isobutane is reacted with carbon monoxide using sulfated zirconia as the catalyst to produce methylisopropyl ketone. The oxygenated hydrocarbon can subsequently be hydrogenated to give a reduced oxygenated saturated hydrocarbon. The hydrogenation can also be done simultaneously with the carbonylation, i.e., reductive carbonylation.
