Microwave-assisted synthesized SAPO-56 as a catalyst in the conversion of CO2 to cyclic carbonates

SAPO-56 crystals were synthesized via microwave heating. The resultant crystals displayed high catalytic activity in the synthesis of chloropropene carbonate from CO2 and epichlorohydrin. The enhanced catalytic activity of SAPO-56 crystals was related to their high CO2 adsorption capacity, small crystal size, and the presence of acid sites.
