  • Process for production of alumina
    Patent number: 4744974
    Abstract: A process for producing alumina wherein an aluminum trialkyl is reacted with a substantially water immiscible alcohol to produce an aluminum alkoxide and an alkane, the reaction between the aluminum trialkyl and the alcohol being conducted in an organic phase, the alkoxide being hydrolyzed in an aqueous phase which is in contact with the organic phase, the alumina formed by hydrolysis of the aluminum alkoxide being recovered from the aqueous phase.
    Type: Grant
    Filed: September 23, 1986
