应用气相色谱 红外光谱(GC FTIR)和气相色谱 质谱(GC MS)对合成松油醇及其杂质成分、原料松节油、合成过程中间体粗油(红油和黄油)和天然松油醇进行了分析研究,为判断松油醇产品中杂质产生的原因及改进生产工艺提供了依据。研究结果表明,松油醇中的杂质主要为长叶烯和石竹烯,是由原料松节油带入的。天然松油醇粗油中主要成分是1,8 桉叶素、反式 4 艹守醇、p 异丙烯基甲苯、顺式 4 艹守醇、芳樟醇、樟脑、龙脑、4 松油醇、α 松油醇和黄樟素。天然松油醇中β 松油醇和γ 松油醇含量不如合成松油醇中的含量高,以此可判断松油醇是天然的还是合成的。
The synthetic terpineol and its impurities, the raw material turpentine, intermediate crude oil (oil and butter) and natural terpineol were analyzed by gas chromatography-mass spectrometry (GC-FTIR) and gas chromatography-mass spectrometry (GC-MS) Research, to determine the causes of impurities in terpineol products and to provide a basis for improving the production process. The results show that the main impurities in terpineol are longifolene and caryophyllene, which is introduced by the raw material turpentine. The main components of natural terpineol crude oil is eucalyptol, trans-4 alcohol, p-isopropenyl toluene, cis-4 alcohol, linalool, camphor, borneol, 4 Terpineol , Alpha terpineol and safrole. The content of β-terpineol and γ-terpineol in natural terpineol is not as high as that of synthetic terpineol, so it can be judged whether terpineol is natural or synthetic.
