title: [Determination of 2,5-ditertiary butylhydroquinone by gas chromatography].
abstract: 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.
