本文研究了氢型丝光沸石催化的双戊烯和萜品油烯的甲氧基化反应。双戊烯甲氧基化反应的主产物是α-松油甲醚,其次是顺-1,8-二甲氧基对(艹孟)烷(9),反-1,8-二甲氧基对(艹孟)烷(10),1-甲氧基对(艹孟)-3-烯(5)。萜品油烯甲氧基化反应的主要醚化产物是(5)、α-松油甲醚、(9)、(10)及8-甲氧基对伞花烃。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, the methoxylation of dipentene and terpinolene catalyzed by hydrogen mordenite was studied. The main product of the dipentene methoxylation reaction is α-pinene methyl ether followed by cis-1,8-dimethoxy p-menthane (9), trans-1,8-dimethoxy Alkali (acenaphthene) alkane (10), 1-methoxy p-menthane-3-ene (5). The major etherification products of terpinolene methoxylation are (5), alpha-terpinene, (9), (10) and 8-methoxy p-cymene. The structure of these etherified products was confirmed by IR, NMR and MS. In addition, the influence of reaction temperature and reaction time on the product distribution was also investigated, and the possible reaction mechanism was also discussed.
