Abstract

A hydroformylation process by reaction between at least one alkene and a gaseous mixture comprising at least carbon monoxide and dihydrogen in the presence of porous catalytic capsules dispersed in at least one organic liquid phase L1. Said porous catalytic capsules, formed from a Pickering emulsion, consist of a liquid core comprising at least one liquid phase L2 comprising at least said hydroformylation catalyst and a porous crust formed by solid particles crosslinked by a crosslinking agent.
