Purification of alcohol

摘要

Primary alcohol containing impurities which have internal hydroxyl groups is purified to cause removal of such internal hydroxyl groups with reduced formation of ethers by treating the impure alcohol with an alumina catalyst which has been contacted with a hydroxide of a Group 1-A element. Preferably the alcohol treatment is concurrent with or followed by a hydrogenation treatment the purpose of which is to improve the iodine number of the treated alcohol.
