Determination of 2,5-Ditertiary Butylhydroquinone by Gas Chromatography
气相色谱法分析2，5-二叔丁基氢醌

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.
