anisoli

Anisole, also known as methyl phenyl ether or methoxybenzene, is an organic compound with the chemical formula C6H5OCH3. It is a clear, colorless liquid with a distinct anise-like odor, which is the source of its common name. Anisole is structurally a derivative of benzene, where a hydrogen atom is replaced by a methoxy group (-OCH3). This ether functionality makes it relatively stable but also susceptible to certain chemical reactions.

The compound is produced industrially through the Williamson ether synthesis, reacting sodium phenoxide with methyl halides, or by the methylation of phenol using dimethyl sulfate or methyl chloride under basic conditions. Anisole finds application as a solvent in various organic reactions, particularly in perfumery and flavor industries due to its pleasant aroma. It also serves as a starting material or intermediate in the synthesis of more complex organic molecules, including pharmaceuticals and agrochemicals.

Anisole is sparingly soluble in water but miscible with most organic solvents like ethanol and diethyl ether. Its physical properties include a boiling point of 154 °C and a melting point of -37 °C. While generally considered to have low toxicity, prolonged exposure to anisole vapor can cause irritation to the respiratory system and eyes. It is combustible and should be handled with appropriate safety precautions.
