PROCESS FOR PREPARING OF ALUMINUM ALCOHOLATES Russian patent published in 1994 - IPC

Abstract RU 2005711 C1

FIELD: production of high-purity aluminum. SUBSTANCE: product- aluminum alcoholates of formula I Al/OR/₃, wherein R- C₄-C₈ alkyl. Selectivity 99.05-99.95 % . Reagent 1: metallic aluminum. Reagent 2- aliphatic C₄-C₈ alcohol containing 0.1-9.5 % by weight of water. Reaction conditions: addition of reagent 2 at rate which allows the temperature conditions to maintain not less than 165 C followed by evaporation of water containing in alcohol at a time as azeotrope due to exothermic alcoholysis reaction. EFFECT: enhanced efficiency. 1 tbl
