    Abstract: An object of the present invention is to provide a highly safe absolute alcohol of high quality free from an off-odor and a method for producing the same. The present invention provides 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. According to the present invention, 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.

The intermediate complex and/or lactate salt may be separated from its aqueous reaction mixture prior to its pyrolysis to reduce the ultimate separation of ethanol from water. Alternatively, the metal of the metal salt may be one whose carbonate decomposes to metal oxide and carbon dioxide during the pyrolysis step of the process to generate said metal salt in situ.

  • Patent number: 4219685
    Abstract: Methods for deodorizing lower alcohols such as ethanol and isopropyl alcohol and their oxy derivatives such as ethers and esters are disclosed, including contacting these compounds with a deodorizing contact mass comprising, on a support, metals and/or metal oxides, preferably of the metals of Group IB, VIB and VIII of the Periodic Table, where the metal oxides are at least partially reduced to metal and the deodorizing contact mass has a minimum particle dimension of greater than about 0.254 mm so as to be in a form suitable for use in a fixed bed contacting process. In a preferred embodiment, isopropyl alcohol is deodorized employing such deodorizing contact masses, preferably comprising Group VIII metals such as nickel, iron, cobalt and the like, on a support, so that the contact mass has a surface area less than about 1,500 m.sup.2 per gram.
