Abstract

Procédé permettant de récupérer du fluorure de bore dans un résidu gazeux impur de fluorure de bore, qui consiste (a) à introduire ledit résidu gazeux impur contenant comme impureté du dioxyde de sulfure dans un mélange d'acide borique et d'acide sulfurique, où le mélange acide absorbe le fluorure de bore dudit résidu gazeux impur et n'absorbe pas, ou très peu, le dioxyde de sulfure contenu dans ledit résidu gazeux; et (b) à retirer du mélange acide le dioxyde de sulfure non absorbé. La présente invention décrit également un procédé de préparation et de purification du fluorure de bore. Ledit procédé consiste (a) à faire réagir de l'acide borique et de l'acide fluorosulfurique dans un acide sulfurique pour en faire un produit, (b) à distiller ledit produit de (a) pour obtenir du fluorure de bore pur et du fluorure de bore gazeux impur; (c) à mélanger ledit résidu gazeux impur de fluorure de bore contenant comme impureté du dioxyde de sulfure avec un mélange d'acide borique et d'acide sulfurique, où le mélange d'acides absorbe le fluorure de bore dudit résidu gazeux impur mais n'absorbe que très peu de dioxyde de sulfure; et (d) à retirer dudit mélange d'acides le dioxide de sulfure non absorbé. On peut utiliser le fluorure de bore ainsi récupéré comme catalyseur.
