Popis: Anthraquinone is a valuable organic intermediate commonly prepared by the reaction of phthalic anhydride with benzene and subsequent acid cyclization of the product obtained. Rapid, sensitive and selective analytical methods are essential for monitoring the reactions during process development. A gas Chromatographic method using an internal standard is described for the separation and determination of the reaction products obtained during the manufacture of anthraquinone.
