Abstract
We have described that both homogeneous and a silica-supported hexaalkylguanidinium chloride were effective catalysts for CO2 fixation to carbonate without any solvent under mild reaction conditions (4.5 MPa, 120 °C, 4 h), the silica-supported hexaalkylguanidinium chloride showing the great advantage that it could be recycled easily at least 5 further times without any obvious decrease in its catalytic activity, after simple filtration.Keywords
