A safe and reliable method of decomposing halogenated aromatic compounds. wherein a heat-resistant alkaline polar solvent containing halogenated aromatic compounds is contacted with a alkali at a temperature ranging from about 100° C to 300° C in order to decompose the halogenated aromatic compounds. The used solvent is removed of solid contents of salts, alkalis and the like, whereby it can be recycled.
Méthode de décomposition de composés aromatiques halogénés en sécurité et sans risque d'échec, cette méthode consistant à amener une solution d'un composé aromatique halogéné au contact, dans un solvant polaire résistant aux bases à chaud, avec une substance basique sous une température de 100 à environ 300 DEG C pour décomposer ce composé aromatique et extraire le sel et la substance basique précipités dans le solvant afin de recycler le solvant utilisé.
