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。 Heteropoly acid (HPA) can effectively catalyze the cracking of rosin, the main product is a neutral, non-volatile oil. The composition of the product was analyzed by gas chromatography / mass spectrometry (GC / MS) technique and a total of 67 peaks were separated. Most of the compounds were identified by comparison with the database standard map. Among them, 21 compounds The content is high, accounting for 88.2% of the total content of oil, mainly by the cracking and oxidation of rosin cycloolefin, aromatic hydrocarbons and aromatic ketones.
