Abstract
A method for producing an absolute alcohol containing not more than 0.4 mg/L of acetal by subjecting a raw material alcohol to a zeolite membrane treatment, the raw material alcohol being obtained by distilling a crude alcohol, and having an alcohol concentration of not less than 95 v/v%, and the raw material alcohol containing not more than 5 mg/L of acetaldehyde and not more than 60 mg/L of a total amount of organic impurities. An absolute alcohol can be produced, which absolute alcohol is highly safe to the human body and has a quality that no off-odor is felt by human senses. In addition, the contents of diacetyl and crotonaldehyde in the raw material alcohol may be set at levels not more than particular values, respectively.
