摘要： 研究了微波辐射下α-蒎烯与甲醇的加成反应。将0.03mol的α-蒎烯、0.12mol甲醇、1.34mmol硫酸在功率70W的微波辐射下反应100min,主产物α-松油基甲醚的得率可达42.5%,选择性为44.7%,反应速率比加热回流条件下提高了近4倍,主产物的得率和选择性都有一定的提高。结果表明,微波辐射技术应用于α-松油基甲醚的合成,反应时间较短、产物得率较高,具有一定的应用价值。

Abstract: Addition reaction between α-pinene and methanol under microwave irradiation was studied, and the optimum experiment factors are as follows: α-pinene 0.03 mol, methanol 0.12 mol, sulfuric acid (catalyst) (1.34 mmol,) microwave power 70 W and reaction time 100 min. The yield of the main product methyl α-terpinyl ether in the reaction mixture reaches 42.5% under the optimum experiment conditions. The reactions under microwave irradiation not only have reaction rate 4 times higher than that by conventional heating method, but also have better productivity and selectivity. The application of microwave technique in the synthesis of methyl α-terpinyl ether has the advantages of high yield and short time, with the potential of extensive utilization.

Key words: microwave irradiation, α-pinene, methyl α-terpinyl ether
