Glycerol carboxylation to glycerol carbonate in the presence of rhodium complexes with nitrogen-containing macroligands
Abstract The carboxylation of glycerol to glycerol carbonate (GC) in the presence of rhodium complexes with N-containing macroligands (polyethyleneimine and chitosan) has been studied. It has been found that the {RhCl3 + chitosan} system is an effective catalyst. It is most effective in the presence of methyl iodide or in the case of introduction of carbonates (dimethyl carbonate, propylene carbonate) into the reaction zone. The carboxylation of glycerol occurs at temperatures of 140–180°C in a methanol solution in a reducing environment under a pressure of 50 atm (40 atm of CO and 10 atm of H2). The turnover number of the rhodium catalyst for the reaction time is 10 to 120.
