DABCO (1,4-diazabicyclo[2.2.2]octane) was immobilized on the surface of polymer resin and used as a heterogeneous catalyst for the transesterification of dimethyl carbonate with glycerol to produce glycerol carbonate. The prepared catalysts were characterized using solid-state 13C-NMR, and IR. The results showed the DABCO was successfully immobilized on the surface of the polymer resin. Acid-base titration of poly-DABCO revealed 2.17 mmol/g of basic site exist on the prepared catalyst. The prepared DABCO-anchored polymer resin could be reused at least 5 times without losing its catalytic activity. The effect of reaction conditions such as reaction time, DMC/glycerol molar ratio, reaction temperature, and catalyst amount were also discussed.
