摘　　要：利用微波催化合成仪,研究了在微波辐射条件下以甲醇和叔丁醇合成甲基叔丁基醚的反应。考察了微波功率、辐射温度、辐射时间、催化剂等因素对转化率的影响。通过实验确定了最佳工艺条件:最佳微波功率为200W,辐射温度75℃,辐射时间为24min,15%硫酸为催化剂,收率为60%。产品经红外光谱、质谱、拉曼光谱、核磁共振等方法测定与表征,证实与目标产物完全一致。该方法具有反应过程简便、反应时间短、产物收率高等特点。Methyl tert-butyl ether was synthesized from methanol and tert-butyl alcohol under the microwave irradiation. Effects of microwave irradiation power, iradiation temperature, iradiation time, and catalyst on reaction were studied. The optimal synthesis conditions were obtained as follows： microwave irradiation power 200 W, radiation temprature 75 ℃, radiation time 24 rain, 15% sulfuric acid as catalyst. The yield of methyl tert-butyl ether can reach 60%. The product is characterized and verified by various methods including FI-IR, Raman spectrum, NMR and MS, which confirm the structure of objective molecule. This method shows the characteristics of simple reaction process, short reaction time, and high product yield.
