摘要
由氢醌与叔丁醇反应制得抗氧化剂２，５－二叔丁基氢醌。采用ＯＶ－１０１弹性石英毛细管柱和火焰离子检测器，用气相色谱归一化法测定了２，５－二叔丁基氢醌，并分析了其中所含氢醌、叔丁基氢醌、叔丁基对苯醌和２，５－二叔丁基对苯醌等杂质。
Antioxidant 2,5\|ditertiary butylhydroquinone was prepared from hydroquinone and tertiary butyl alcohol. A normalized gas chromatographic method for 2,5\|ditertiary butylhydroquinone by using an OV\|101 fused silica capillary column and flame ionization detector is reported. The quantities of hydroquinone, tertiary butylbenzoquinone, tertiary butylhydroquinone and 2,5\|ditertiary butylbenzoquinone mixed with 2,5\|ditertiary butylhydroquinone were also determined.
