Methyl tert-butyl ether was synthesized from methanol and tea-butyl alcohol under the microwave irradia-tion. 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 min, 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.
