Description
Pure ethanol that contains less than one percent of water. Ethyl alcohol is miscible in water at all proportion and distills as an azeotrope (constant boiling mixture) containing 5% water. For complete dehydration, ethanol is mixed with Mineral spirits, turpentine, or Quicklime and redistilled. Absolute alcohol is often preferred as a solvent for lacquers since they dry clearer and harder in the absence of moisture. Absolute alcohol is strongly Hygroscopic and will reabsorb water from the air in an open container.
