Title
Synthesis of glycerol carbonate from the transesterification of dimethyl carbonate with glycerol using DABCO and DABCO-anchored Merrifield resin
Abstract

•DABCO afforded much higher GLC yield than other polyamines.•DABCO is successfully immobilized onto Merrifield resin ([p-DABCO]Cl).•[p-DABCO]Cl showed high transesterification activity and reusability.•Mechanism of the transesterification of glycerol with DMC was investigated.

Both DABCO (1,4-diazabicyclo[2.2.2]octane) and Merrifield resin-anchored DABCO ([p-DABCO]Cl), prepared from the reaction of DABCO and Merrifield resin, were found to exhibit high activities for the transesterification of dimethyl carbonate (DMC) with glycerol to produce glycerol carbonate (GLC). FT-IR and NMR spectroscopic results suggest that such a high transesterification activity of DABCO could be attributed to its superior ability to activate glycerol via a strong hydrogen bond formation between a hydroxyl group of glycerol and an amino group of DABCO. Meanwhile, the activation of glycerol by [p-DABCO]Cl proceeds mainly through the hydrogen bond interaction between a hydroxyl group or groups of glycerol and Cl− of [p-DABCO]Cl. The catalytic activity of [p-DABCO]Cl was maintained up to 5 reuses, demonstrating that [p-DABCO]Cl could be used as a recyclable heterogeneous catalyst.
