摘　　要：本文用高温液晶芳香羧酸酯作固定相,经气相色谱法直接分离了2-辛醇与苯酚的反应产物。GC-MS及合成的标准样品证明为1-甲基庚基苯酚、1-乙基已基苯酚及1-丙基戊基苯酚的邻位和对位异构体组成。研究了柱温对调整保留时间和柱效能的影响,讨论了“过冷”现象,并对不同催化体系的反应产物进行了定量分析。Identification of reaction products of phenol with octanol-2 by gas-liquid ehromato- graphy using aromatic carboxylates type liquid crystal as stationary phase was reported. The reaction product was proved to be a mixture of o-and p-isomers of l-methylheptyl- phenol, l-ethylhexylphenol and l-propylamylphenol as shawn by GC-MS studies in comparison with authentic specimen. The effect of temperature of column on its efficiency as well as on the adjusted reteution time was also evaluated. The supercooling phenome- non was observed. In the meantime, a quantitative estimation of reaction products from various catalyst systems was performed.
