ABSTRACT:
It is disclosed that a process wherein a reducible compound is reduced by an addition reaction to aluminum dihydrocarbon dihydrides of sodium, potassium or lithium followed by hydrolysis to remove the aluminum is improved by subjecting to oxidation with molecular oxygen the product from the aluminum addition prior to the hydrolysis operation. The intervening oxidation operation converts al--R bonds in the addition product into al-O-R bonds, R being hydrocarbon, preferably alkyl, the result being that upon hydrolysis an alcohol is produced from those groups rather than a hydrocarbon. The by-product alcohol thus produced is easier to dispose of without serious ecological disadvantages which is a significant improvement over the situation that exists when hydrocarbon is released.
