摘　　要：杂多酸（HPA）催化松香裂解的产物为油状物，本文利用气相色谱/质谱（GC/MS）联用技术对该产物的挥发组分进行了分析，共分离出177个峰；通过与数据库标准图诺对照鉴定出绝大部分组分。其中有28种组分含量较高，占挥发成分总含量的51．52％，主要为松香裂解产生的C6-C20的烯烃。The essential oil from cracked rosin over the heteropoly acid catalysts was analyzed by GC/MS. 177 peaks were separeted by GC and identified by using mass spectral data and the registry of mass spectral data, in which 28 compounds represented over 51. 52% of the peak area on total ionic current of the essential oil. The main components were alkenes, aromatic hydrocarbon and ketones from C6 ~ C20.
