[0002] Phenol is a colorless needle-shaped crystal with a special smell. It is toxic and can be used as an important raw material for the production of certain resins, bactericides, preservatives and drugs (such as aspirin). It can also be used for disinfecting surgical instruments and treating excrement, skin sterilization, itching and otitis media. Therefore, it is an important raw material for medical drugs.

[0003] In the process of producing certain acid esters, water vapor containing phenol is generated.
