Properties:
Phenol exhibits weak acidity due to the direct attachment of its hydroxyl group to the benzene ring. It reacts with sodium hydroxide, but its acidity is weaker than that of carbonic acid. The hydroxyl group strongly activates the ortho and para positions of the benzene ring, making its electrophilic substitution reactions (such as bromination and nitration) readily occur, often yielding trisubstituted products. Furthermore, phenol is easily oxidized by air, resulting in a discoloration, and it exhibits a characteristic purple color reaction with ferric chloride solution.
Application:
Phenol is an important chemical intermediate, mainly used in the synthesis of phenolic resins, bisphenol A, and caprolactam, which in turn produce polymer materials such as plastics, epoxy resins, and nylon. In the fine chemical industry, it is used to prepare salicylic acid, pesticides, dyes, and surfactants. Historically, it was used as a disinfectant (carbolic acid), but now it is more commonly used as a raw material for chemical synthesis.
