Dual role for CO 2 : Pure formic acid can be obtained continuously by hydrogenation of CO 2 in a single processing unit (see scheme). An immobilized ruthenium organometallic catalyst and a nonvolatile base in an ionic liquid (IL) are combined with supercritical CO 2 as both reactant and extractive phase.
