Chemical and Physical Properties of the Ethanol Molecule
The chemical compound ethanol, also known as ethyl alcohol or grain alcohol, is the bio-alcohol found in alcoholic beverages. When non-chemists refer to "alcohol", they almost always mean ethanol. It is also increasingly being used as a fuel (usually replacing or complementing gasoline). Ethanol's chemical formula is C2H5OH.
Properties
Pure ethanol is a flammable, colorless liquid with a boiling point of 78.5° C. Its low melting point of -114.5° C allows it to be used in antifreeze products. It has a pleasant odor reminiscent of whiskey. Its density is 789 g/l about 20% less than that of water. It is easily soluble in water and is itself a good solvent, used in perfumes, paints and tinctures. Alcoholic drinks have a large variety of tastes, since various flavor compounds are dissolved during brewing. >A solution of 70-85% of ethanol is commonly used as a disinfectant; it kills organisms by denaturing their proteins and dissolving their lipids: it is effective against most bacteria and fungi, and many viruses, but is ineffective against bacterial spores. This disinfectant property of ethanol is the reason that alcoholic beverages can be stored for a long time.
Ethanol can lose a proton from the hydroxyl group and is a very weak acid, weaker than water. The CAS number of ethanol is 64-17-5 and its UN number is UN 1170.
Ethanol as fuel
Ethanol is flammable and burns more cleanly than many other fuels. When fully combusted its combustion products are only carbon dioxide and water. For this reason, it is favoured for environmentally conscious transport schemes and has been used to fuel public buses. However, pure ethanol attacks certain rubber and plastic materials and cannot be used in unmodified car engines. Additionally, ethanol has a much higher octane rating than ordinary gasoline, requiring changes to the spark timing in engines.
