Description:
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 {RhCl 3 + 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 H 2 ). The turnover number of the rhodium catalyst for the reaction time is 10 to 120. Content Type Journal Article Pages 416-421 DOI 10.1134/S0965544112060060 Authors N. N.
