α──蒎烯正离子齐聚反应中二聚体的研究

Study on the Dimer in Cationic Oligomerization of α-Pinene

本文建立了从α－蒎烯齐聚物中提取高约二聚体的方法，并采用柱层析法对α－蒎烯二聚体异构体进行分离，通过ＮＭＲ（１３Ｃ－ＮＭＲ、１Ｈ－ＮＭＲ），ＩＲ、ＵＶ手段，对α－蒎烯二聚体主要异构体进行了表征，推测了其生成机理。

The method for extracting the dimer with high purity from α－pinene oligomer is introduced in this paper.The α-pinene dimer isomers which can be separated by column chromatography, are characterized by NMR (13C-NMR, 1H-NMR), IR,UV; and thus, its reaction mechanism can be inferred.
