Abstract
Process for the production of glycolic acid by contacting carbon monoxide and formaldehyde with a catalyst containing an acidic polyoxometalate compound encapsulated within the pores of a zeolite. The zeolite has cages larger than the acidic polyoxometalate compound, and has pores with a diameter smaller than the diameter of the acidic polyoxometalate compound.
