Abstract

L'invention appartient au domaine de la chimie organique et concerne des procédés de fabrication de trifluorure d'azote. Selon le procédé, on effectue la fluoration du sel de polyfluorure d'ammonium en phase solide, correspondant à la formule NH4F.xHF dans laquelle 'x ' est supérieur à 0 et inférieur ou égal à 1,3, on utilise le sel de départ dans un mélange avec le sorbant capable d'absorber le fluorure d'hydrogène, formé par le synthèse, ledit sorbant se présentant comme des fluorures des métaux des groupes MeF dans lesquels Me est un métal du groupe I du tableau périodique, de préférence NaF, KF, LiF. On peut également utiliser RbF et CsF, mais leur utilisation n'est pas justifiée économiquement. Le procédé de fabrication du trifluorure d'azote est mis en oeuvre à 20-125 °C. On parvient à utiliser complètement le sel de départ NH¿4F?.xHF et à évacuer le fluorure d'hydrogène obtenu.
