Chemical Description

  • Ethanol, also known as ethyl alcohol (or grain spirits, or alcohol), is a clear colorless, volatile, flammable solvent with a characteristic odor. The boiling point of ethanal is 78.5°C.
  • Bio-alcohol is found in alcoholic beverages. Concentrated alcohol has a strong burning taste, but it is somewhat sweet when diluted.
  • It is also increasingly being used as a fuel (usually replacing or complementing gasoline). Its low melting point of -114.5° C allows it to be used in antifreeze products.
  • Ethanol is highly soluble in water and organic solvents, but poorly soluble in fats and oils. Ethanol itself is a good solvent, which is used in cosmetics, paints and tinctures. Density of ethanol at 68 °F (20 °C) is 789 g/l. Pure ethanol is neutral (pH ~7).
  • Most alcoholic beverages are more or less acidic.
  • Ethanol/ethyl alcohol is a highly flammable liquid, hygroscopic, and fully miscible in water.
  • Ethanol is incompatible with a large number of chemicals such as strong oxidizing agents, acids, alkali metals, ammonia, hydrazine, peroxides, sodium, acid anhydrides, calcium hypochlorite, chromyl chloride, nitrosyl perchlorate, bromine pentafluoride, perchloric acid, silver nitrate, mercuric nitrate, potassium tert-butoxide, magnesium perchlorate, acid chlorides, platinum, uranium hexafluoride, silver oxide, iodine heptafluoride, acetyl bromide, disulfur difluoride, acetyl chloride, permanganic acid, ruthenium (VIII) oxide, uranyl perchlorate, and potassium dioxide.
  • A solution of 70-85% of ethanol is commonly used as a disinfectant and 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 also has many medical uses, and can be found in products such as medicines, medical wipes and as an antiseptic in most antibacterial hand sanitizer gels. Ethanol can also be used as an antidote. It competitively blocks the formation of toxic metabolites in toxic alcohol ingestions by having a higher affinity for the enzyme Alcohol Dehydrogenase (ADH).
  • Its chief application is in methanol and ethylene glycol ingestions. Ethanol can be administered by the oral, nasogastric or intravenous route to maintain a blood ethanol concentration of 100-150 mg/dl (22-33 mol/L).
