| Abstract: | The synthesis of dimethyl carbonate from phenol and CO2 was studied with magnesium as catalyst in high pressure reaction kettle.Through the single-factor and orthogonal experiments,it is showed that the successive order of different factors influencing the synthesis of dimethyl carbonate is reaction temperature> reaction time> reaction pressure.The optimal conditions are that the reaction temperature is 180 ℃,the reaction time is 7 h,and the reaction pressure is 7.5 MPa. |
