Process for production of alumina
Patent
·
OSTI ID:7203467
A process for the production of alumina, is described comprising: reacting an aluminum trialkyl with a substantially water immiscible alcohol to produce aluminum alkoxide and alkane; hydrolyzing the aluminum alkoxide to produce the alcohol and alumina, the reaction between the aluminum trialkyl and the alcohol being conducted in an organic phase, the hydrolysis of the aluminum alkoxide being conducted in an aqueous phase, the organic phase and the aqueous phase being contiguous, the reacting of the aluminum trialkyl with the alcohol and the hydrolyzing being conducted in a single, common reaction zone, and recovering the alumina.
