Direct amination of alcohols with heteropoly acids

摘要

The present invention describes a process for preparing amines by reacting a alcohol with an aminating agent in presence of a catalyst, whereby said catalyst is a heteropoly acid comprising a transition metal, and/or a salt thereof. Preference is given to using glycerol. The preferred transition metal of said heteropoly acid is preferably selected from the group of tungsten, molybdenum and/or vanadium. Said heteropoly acid further comprises a non-metal, preferably from the group of silicon, phosphorus, germanium and/or vanadium. The heteropoly acid is preferably supported by silica. This invention provides industrial important aminoderivatives.
