Abstract

Procédé de production de naphtalène raffiné de qualité non décolorante pour boules de naphtaline, à partir d'huile de naphtalène brute dérivée de la houille. Ce procédé évite un nombre important d'étapes intermédiaires, l'épuration du naphtalène ne requiert pas d'acide sulfurique et les problèmes de dégradation de l'environnement liés au rejet des boues acides sont évités. Ce procédé consiste à cristalliser le naphtalène contenu dans une solution d'huile de naphtalène et de méthanol et à l'épurer au moyen d'argile.Process for the production of refined naphthalene of non-bleaching quality for naphthalene balls, from crude naphthalene oil derived from coal. This process avoids a large number of intermediate stages, the purification of naphthalene does not require sulfuric acid and the problems of environmental degradation linked to the rejection of acid sludge are avoided. This process consists in crystallizing the naphthalene contained in a solution of naphthalene oil and methanol and to purify it by means of clay.
