CA 2056041
his invention involves a procedure for synthezising azines from hydrogen peroxide, ammonia and a reactant carrying a carbonyl group, in the absence of any mineral or organic catalyst, characterized by the fact that the reactant is brought into contact with an amide derived from a corresponding carboxylic acid whose dissociation constant is less than 5 x 10-5, and the ammonium salt corresponding to this acid, and the azine obtained is then separated. The invention also involves procedures in which the reaction occurs in the presence of any mixtures containing an amide with subsequent recovery of the azine and treatment of the remaining reaction environment to regenerate the amide.
La présente invention concerne procédé de synthèse d'azines à partir d'eau oxygénée, d'ammoniac et d'un réactif portant un groupe carbonyle, en l'absence de tout catalyseur minéral ou organique, caractérisé en ce qu'on met en contact ce réactif avec un amide dérivé d'un acide carboxylique correspondant dont la constante de dissociation est inférieure à 5 x 10-5, et le sel d'ammonium correspondant à cet acide puis qu'on sépare l'azine obtenue. L'invention concerne aussi des procédés dans lesquels la réaction se fait en présence de tout mélange contenant un amide puis on récupère l'azine et le reste du milieu réactionnel est traité pour régénérer l'amide.
