Solution properties of ethanol in water - ScienceDirect

WebMar 31, 2024 · The answer has to do with the different sizes of the water and ethanol molecules. Ethanol molecules are smaller than water molecules, so when the two liquids are mixed together the ethanol falls between the spaces left by the water. It's similar to what happens when you mix a liter of sand and a liter of rocks. WebWhen boiling an ethanol-water azeotrope, the boiling point of 100% pure ethanol can never be reached since the 96/4 mixture boils first. By adding benzene (warning: toxic!) 100% pure ethanol can be produced, since the benzene forms an azeotrope with the water, which can then be extracted. Nowadays molecular sieves provide a much healthier way ... blw87
