| Abstract: | The synthesis of propylene carbonate (PC) from propylene oxide and CO2 in the presense of newMC-3 catalyst was studied. The experiments were optimized in the study by Uniform Design and theoptimum reaction conditions obtained were as follows: temperatare 135C, pressure 3. OMPa, catalystconcentration 0.0011 (mole ratio), stirring rate 916 rpm. The activity of MC-3 is 3. 49 mol/mol .min andthe yield of PC is over 97%. Its reaction mechanism was also discussed in this paper. |
