摘要
本文研究了氢型丝光沸石催化的双戊烯(2)和异松油烯(4)的甲氧基化反应。2甲氧基化反应的主产物是α-松油甲醚(8),其次是顺-1,8-二甲氧基对(?)烷(9)、反-1,8-二甲氧基对(?)烷(10)、1-甲氧基对(?)-3-烯(5)。4甲氧基化反应的主要醚化产物是5、8、9、10及8-甲氧基对伞花烃(12)。这些醚化产物的结构由红外、核磁、质谱确定。此外,还考察了反应温度和反应时间对产物分布的影响,探讨了可能的反应机理。
In this paper, H-mordenite-catalyzed methoxylation of dipentene ( 2 ) and terpinolene ( 4 ) have been studied. The major product of methoxylation of ( 2 ) is Me α-terpinyl ether ( 8 ). Other products are cis-1, 8-di-methoxy-p-menthane (9), trans-1, 8-dimethoxy-p-menthane (10), 1-me-thoxy-p-menth-3-ene ( 5 ) , Main etherification products of methoxylation of 4 are 5 , 8 , 9 ,10 and 8-methoxy-p-cymene (12) . The structures of
these products are confirmed by IR, 1H NMR and MS spectra. The influence of reaction temperature and time on the product distributions has
also been examined and probable mechanisms have been proposed.
