In daily life, we may often hear the three nouns ethanol, acetaldehyde and acetic acid. They are all organic compounds made of ethylene molecules through different chemical changes. So, what kind of connection and difference exists between the three? Here we come to introduce one by one.

ethanol, also known as "alcohol", is a colorless, flammable liquid. Ethanol molecule consists of two carbon atoms, six hydrogen atoms and one oxygen atom. It is an organic substance that is soluble in water and has the general properties of an alcohol. Common uses of ethanol include pharmaceuticals, beverages, cosmetics and fuels. In the field of medicine, ethanol can be used for sterilization; in the field of beverages, ethanol is the main component of beer, wine and spirits; in the field of cosmetics, ethanol is used to adjust viscosity, stability and enhance product transparency; in the field of fuel, ethanol can be used as biofuel to generate electricity.

acetaldehyde, also known as acetaldehyde, is an organic solvent whose molecule consists of two carbon atoms, four hydrogen atoms and one oxygen atom. Acetaldehyde is a liquid with a pungent odor, and common uses include the production of dyes, resins, and plastics, as well as the manufacture of pesticides and pharmaceuticals. In the production of dyes, resins and plastics, acetaldehyde is used as a solvent and synthetic raw material; in the field of pesticides and pharmaceuticals, acetaldehyde is an important intermediate for the synthesis of other organic compounds.

acetic acid, also known as acetic acid, is a colorless liquid with a pungent odor. The acetic acid molecule consists of two carbon atoms, four hydrogen atoms and two oxygen atoms. Acetic acid is a commonly used food additive, which can enhance the sour taste and fresh-keeping effect of food. In addition, acetic acid is also widely used in coatings, solvents and pharmaceutical industries.

through the above introduction of ethanol, acetaldehyde and acetic acid, we can see that although they are made of ethylene molecules through different chemical reactions, but their structure and properties have significant differences. Ethanol has the properties of alcohol and is commonly used in the fields of medicine, beverage, cosmetics and fuel; acetaldehyde is an organic solvent, mainly used in the production of dyes, resins and plastics; acetic acid is a food additive, and is also widely used in industrial fields such as coatings, solvents and pharmaceuticals.

hope that through the introduction of this article, readers can more clearly understand the difference between ethanol, acetaldehyde and acetic acid, and their applications in industry and daily life.
