Abstract
A process for continuous carbonylation of carbonylatable reactants with carbon monoxide in the gaseous phase in the presence of a catalyst, wherein said catalyst is a Supported Ionic Liquid-Phase (SILP) catalyst comprising a solution of a Group VIII metal in an ionic liquid confined on a support. The SILP catalyst offers a very large active catalyst area resulting in a very efficient use of catalyst material and a simple apparatus design.
