METHOD OF PRODUCING HIGHLY PURE ALUMINIUM ALKOXIDES Russian patent published in 2010 - IPC C07F5/06 C07C29/70 C07C31/32 

FIELD: chemistry.

SUBSTANCE: method involves reaction of an aliphatic alcohol containing 2-4 carbon atoms with activated aluminium with purity not lower than 99.97% and subsequent purification of the obtained product. The reaction takes place in a tube reactor in which excess aluminium is loaded, where the said aluminium is activated with tin in amount of 0.0025-0.04 wt % of the initial aluminium in the presence of ammonium halides in amount of at least 0.01 wt % of the initial aluminium. The reaction takes place with dosed supply of alcohol into the top part of the reactor. The bottom part of the reactor is heated to temperature which corresponds to melting point of the aluminium alkoxide.

EFFECT: design of an efficient method of producing highly pure aluminium alkoxides which can be widely used, eg as catalysts in various processes in organic chemistry.
