Title (EN) AROMATIC SULFONATION REACTIONS
(FR) REACTIONS DE SULFONATION AROMATIQUE
Abstract: front page image
(EN)A process for the sulfonation of an aromatic compound wherein the aromatic compound and sulfonating agent are admixed in the presence of an ionic liquid is described. The method for the sulfonation of aromatic compounds in (e.g. water stable) ionic liquids offers advantages over conventional sulfonation reactions. These are that no by-products formed, the ionic liquid is not consumed and the sulfonating agent (e.g. SO¿3?) is relatively inexpensive.
(FR)La présente invention concerne un procédé de sulfonation d'un composé aromatique dans lequel le composé aromatique et un agent de sulfonation sont mélangés en présence d'un liquide ionique. Le procédé de sulfonation de composés aromatiques dans des liquides ioniques (de l'eau stable par exemple) offre plusieurs avantages comparativement aux réactions de sulfonation classiques, il n'a y pas formation de sous-produits, le liquide ionique n'est pas épuisé et l'agent de sulfonation (du SO¿3? par exemple) est relativement peu coûteux.
