| 摘 要： | 在常压条件下,采用化学沉淀法制备了纳米二氧化铈(CeO2)材料，应用其催化CO2和甲醇(CH3OH)直接合成碳酸二甲酯(DMC).考察了反应温度、CO2压力和CeO2用量对合成DMC收率的影响，结果表明CH3OH用量为15 mL时,在反应温度140 ℃、CO2压力4.0 MPa、催化剂用量0.15 g的最优条件下，合成收率可达47.9%.

| Abstract: | Under atmospheric pressure,nano-sized cerium dioxide (CeO2) was prepared by chemical precipitation method.Catalyzed by this nano-sized CeO2,dimethyl carbonate (DMC) was synthesized directly from carbon dioxide and methanol (CH3OH).The effects of reaction temperature,carbon dioxide pressure and the dosage of CeO2 on the yield of DMC were investigated.The results showed that the highest yield was 47.9% at 140 ℃ with carbon dioxide pressure 4.0 MPa,catalyst dosage 0.15 g,and the amount of CH3OH 15 mL. |
