2-Ethylphenol: Properties, Uses, and Considerations

2-Ethylphenol, also known as o-Ethylphenol, is an organic compound belonging to the aromatic alcohol family. It’s characterized by a hydroxyl group (-OH) and an ethyl group (-CH2CH3) attached to a benzene ring, with the ethyl group positioned at the ortho (2-) position relative to the hydroxyl group. This seemingly simple structure unlocks a range of interesting properties and uses, making 2-ethylphenol a compound of interest in various industries.

Properties and Characteristics:

• Appearance: Typically exists as a colorless to light yellow liquid at room temperature. Over time, it can darken due to oxidation.
• Odor: Possesses a phenolic odor, which can be described as medicinal or tar-like. This odor can be significant in its applications.
• Solubility: Slightly soluble in water but readily soluble in organic solvents like ethanol, ether, and benzene.
• Boiling Point: With a boiling point around 206-208°C, it’s relatively stable at room temperature, but can be vaporized with heat.
• Reactivity: The presence of the hydroxyl group makes 2-ethylphenol a reactive compound. It can participate in reactions typical of phenols, such as esterification, etherification, and aromatic electrophilic substitution.
