丝光沸石分子筛催化α-蒎烯异构化反应得到莰烯、苧烯、异松油烯、α-松油烯、γ-松油烯、三环烯和β-葑烯等十三种产物。本文主要研究了催化剂交换度、反应温度和催化剂用量对产物分布的影响,以及主要异构化产物莰烯和苧烯的光学活性,并对反应机理做了讨论。 The mordenite zeolite catalyzes the isomerization reaction of α-pinene to obtain thirteen products of camphene, limonene, terpinolene, α-terpinene, γ-terpinene, tricyclene and β-camphene. In this paper, the effects of catalyst exchange degree, reaction temperature and amount of catalyst on the product distribution were investigated. The optical activities of the major isomerization products, acenaphthylene and limonene, were also discussed. The reaction mechanism was also discussed.
