Abstract
The present invention relates to an improved process for the production of perchlorinated quinones by oxidative dehalogenation comprising the steps of providing a stoichiometric mixture consisting of sulfur trioxide, sulfuric acid and at least one aromatic compound containing one or more unsaturated carbon-rings therein. The mixture is reacted with a stoichiometric quantity of chlorine by slowly adding the chlorine to the mixture while stirring. After a sufficient reaction time the resultant perchlorinated quinone product is recovered from the reacted mixture.
