ABSTRACT:
The present invention involves a process for removing water from mixtures of alcohols and water by contacting such a mixture with an ion exchange resin of either the cation or anion type. Prior to use for alcohol dehydration, the ion exchange resin itself is dehydrated if necessary or desired by contacting it with methanol, propanol, isopropanol, acetone or other like low molecular weight hydrophilic solvents. After use for alcohol dehydration, the ion exchange resin is regenerated by contacting it with these regenerating agents.
