Abstract

L'invention concerne un procédé de production de la 1,5-dichloranthraquinone à partir de la 1,5-dinitroanthraquinone par réaction avec du chlore élémentaire. On effectue la réaction à des températures élevées en présence d'anhydride phtalique. On peut opérer à des températures relativement basses et l'on obtient avec de bons rendements des produits ne contenant pratiquement pas de sous-produits. La 1,5-dichloranthraquinone peut servir à fabriquer de nombreux colorants (pour cuves, acides ou dispersables).
