Brief Introduction:
Phenol is an organic compound with a chemical structure of a hydroxyl group attached to a benzene ring. It has the functions of a disinfectant and preservative and is widely used in medicine, chemicals and daily necessities. It is effective against a variety of microorganisms, including certain fungi and viruses, but has a slower effect against spores. Phenol can be used for skin disinfection and itching relief. It is also an important raw material in the pharmaceutical industry, such as for the manufacture of drugs such as aspirin, and is used in the production of plastics, synthetic fibers and cosmetics. However, phenol is toxic and can cause harm to the human body through ingestion, inhalation or skin absorption, and can even be fatal in severe cases. Under certain conditions, phenol can act as an antioxidant to scavenge free radicals and protect food from oxidation. In addition, studies have shown that adsorption treatment using activated carbon can effectively remove phenolic pollutants in water, and its adsorption mechanism involves electrostatic interactions, π-π interactions, electron donor-acceptor mechanisms and hydrogen bonds.
Aromatic Compounds
Phenol is considered an aromatic compound because it contains a benzene ring (C6H5) with a hydroxyl group (-OH) attached to it.
Alcohols
Since phenol contains a hydroxyl group attached to a carbon atom, it is classified as an alcohol, although it's a unique case compared to typical alcohols like ethanol.
Hydroxy Aromatics
This category specifically refers to aromatic compounds that contain a hydroxyl group. Phenol is a classic example.
Organic Acids
Phenol can exhibit weak acidic properties due to the hydrogen ion (proton) donation from the hydroxyl group. This is why it's sometimes referred to as carbolic acid in older texts.
Phenolic Compounds
This category refers to compounds that contain a phenol group, typically characterized by a benzene ring with a hydroxyl group. Many derivatives of phenol fall into this class.
Antiseptics and Disinfectants
Phenol is widely used in disinfectants and antiseptics because of its antimicrobial properties.
