Microwave-assisted Synthesized SAPO-56 as Catalyst in the Conversion of CO2 to Cyclic Carbonates

The synthesis of SAPO-56 crystals via microwave heating assisted method is presented. The resultant crystals displayed high catalytic activity in the synthesis of chloropropene carbonate from CO₂ and epichlorohydrin. This was related to high CO₂ adsorption capacity, and the presence of both Bronsted and Lewis acid sites in its framework.
