Abstract

La présente invention concerne un procédé de préparation par lots ou en continu de HCN anhydre. Ce procédé consiste à faire réagir dans un réacteur un métal alcalin ou des sels de métaux alcalino-terreux de cyanure avec des acides minéraux, cette réaction étant suivie d'un transfert vers une colonne de fractionnement. Il en résulte une faible formation de polymères pour une production élevée de produit.
