VERFAHREN ZUR HERSTELLUNG VON BASISCHEM ALUMINIUMPOLYCHLORID UND SEINE ANWENDUNG FÜR DIE BEHANDLUNG VON WASSERHALTIGEN MEDIA

摘要

Prepn. of alkaline aluminium poly-chloride (I) comprises: (i) mixing a slightly basic aluminium polychloride (reactant A) with an alkali metal aluminate (reactant B) in a mixer; and (ii) dissolving the obtd. ppte. in a reactor. The mixer is upstream of the reactor, and A and B are introduced separately to the mixer as 2 confluent currents. Mixing of A and B takes place in a turbulent flow zone of the mixer.
