Ethanol, acetaldehyde, acetic acid, and ethylamine, these four words often appear in chemistry, but do you truly understand the differences between them? This article will reveal the differences between ethanol, acetaldehyde, acetic acid, and ethylamine, allowing you to have a clear understanding of their characteristics and uses

1、 Ethanol 

Ethanol, chemical formula C2H5OH, is a colorless, flammable liquid. Ethanol is a common name for alcohol, commonly used in wine making, cosmetics, solvents, etc. In medicine, ethanol is also used as a disinfectant. Ethanol is an alcohol compound consisting of an oxygen atom connecting two carbon atoms and a hydrogen atom

2、 Acetaldehyde, chemical formula CH3CHO, is an organic compound. Acetaldehyde is a colorless, flammable liquid with a strong irritating odor. Acetaldehyde is commonly used in industry as a raw material for organic synthesis. In addition, acetaldehyde is also an important organic synthesis reagent

3、 Acetic acid, chemical formula CH3COOH, is an organic compound. Acetic acid is a colorless liquid that can dissolve in water. Acetic acid is a common acidic substance with a pungent odor. Acetic acid is widely used in industries such as pharmaceuticals, food, and dyes

4、 Ethylamine, chemical formula C2H7N, is an organic compound. Ethylamine is a colorless gas with an irritating odor. Ethylamine is an important solvent and intermediate with extensive applications in the pharmaceutical and chemical industries

In summary, ethanol, acetaldehyde, acetic acid, and ethylamine each have differences in their chemical properties, physical properties, and uses. Understanding their differences can help us better understand and apply them to chemistry and related fields.
