Chemical fixation of CO2 to synthesize carbonates is one of the most attractive subjects in synthetic organic chemistry. CO2 is one of the greenhouse gases, it is non-toxic, abundant, and recoverable C1 building block. One of the industrial processes for CO2 utilization is coupling reaction of AGE and CO2 to produce cyclic carbonate, which can be used as aprotic polar solvents, monomers for pharmaceutical and fine chemical intermediates. Polyethylene glycol immobilized ionic liquids (PEG-ILs) were synthesized and evaluated for their catalytic performance in the coupling reaction of AGE and CO2. PEG-ILs was characterized by 1H-NMR, FT-IR and EA. The reaction was carried out in a batch autoclave reactor and the effects of catalyst structure and reaction parameter such as CO2 pressure, reaction temperature, and reaction time were investigated. |
