Fig. 7From: Triphenylphosphine-based functional porous polymer as an efficient heterogeneous catalyst for the synthesis of cyclic carbonates from CO2 Catalytic reusability of TPDB-BP-TEA for cycloaddition of CO2 with PO. As a solid catalyst, TPDB-BP-TEA is recovered readily by filtration or centrifugation and well maintain its activity in the five-run recycling test under mild conditionsBack to article page
