Abstract: front page image
(EN)A process for the nitration of an aromatic compound, wherein the aromatic compound is admixed with a nitrating agent in the presence of an ionic liquid is described. The method for the nitration of aromatic compounds in (e.g. neutral) ionic liquids has advantages over conventional nitrations, such as the only by-product being water, the ionic liquid not being consumed and the nitrating agent being relatively inexpensive.
(FR)L'invention concerne un procédé de nitration d'un composé aromatique, dans lequel le composé aromatique est mélangé avec un agent de nitration en présence d'un liquide ionique. Ce procédé de nitration de composés aromatiques dans des liquides ioniques (par ex. neutres) présente des avantages par rapport aux nitrations classiques. Par exemple, le seul sous-produit est l'eau, le liquide ionique n'est pas consommé, et l'agent de nitration est relativement peu coûteux.
