杂多酸催化松香裂解产物中非挥发性油成分分析

Components of No-Essential Oil in Cracked Rosin Catalyzed by Heteropoly Acids

杂多酸 (HPA)可有效催化松香的裂解 ,其主产物为中性、非挥发性油状物。文章利用气相色谱 /质谱 (GC/MS)联用技术对该产物成分进行了分析 ,共分离出 67个峰 ;通过与数据库标准图谱进行对照 ,鉴定出了绝大部分化合物 ;其中 2 1种化合物含量较高 ,占油状物总含量的 88.2 3 % ,主要是由松香裂解和氧化产生的环烯烃、芳香烃和芳香酮等。

The no-essential oil from cracked rosin over the HPA catalysts are analyzed by GC/MS.67 peaks are separated by GC and were identified by using mass spectral data and the registry of mass spectral data,in which 21 compounds represent over 82.23% of the peak area on TIC of the oil.The main components are cycloolefins,aromatic hydrocarbon and arone.
