摘　　要：用邻苯二甲酸和1,10-癸二醇合成了邻苯二甲酸癸二醇聚酯,并对产物进行了红外光谱和核磁共振氢谱表征,确定了产物的结构。并把产物用静态法制成了毛细管色谱柱,检测了该色谱柱的最高使用温度和其对酚类异构体的分析效果。结果表明:实验成功研制出了30 m×0.25 mm×0.32μm的聚邻苯二甲酸癸二酯毛细管色谱柱,其最高使用温度达到270℃。在柱温为160℃时,对甲酚的理论塔板数达到4000左右,建立了对、间甲酚及3,5-二甲酚的高效分析方法。Decanediol phthalate polyester was synthesized from phthalic acid and decanediol,and its microstructure was characterized by NMR and IR.The capillary column was capped with decanediol glycol phthalate polyester and was then successfully prepared by static method.The separation performance of cresol and xylenol isomers was evaluated and measured by maximum operating temperature examination.The results showed that the capillary column of decanediol glycol phthalate polyester exhibited excellent separation ability of cresol and xylcresol isomers,the highest operating temperature was up to 270℃.The number of theoretical plates per meter was more than 4000(para-cresol)in the 160℃column temperature.A method for the analysis of m-cresol,xylcresol and 3,5-xylenol was established.
