1chloronaphthalene

1-Chloronaphthalene is an organic compound with the chemical formula C10H7Cl. It is a chlorinated derivative of naphthalene, consisting of a naphthalene ring system with a single chlorine atom attached to one of the carbon atoms. It exists as a colorless to pale yellow liquid at room temperature. 1-Chloronaphthalene is a relatively stable compound and is generally insoluble in water but soluble in many organic solvents such as ethanol, ether, and benzene.

This compound is produced industrially through the chlorination of naphthalene. The process typically involves reacting naphthalene with chlorine gas in the presence of a catalyst. Isomers of chloronaphthalene, such as 2-chloronaphthalene, are often produced as byproducts. Separation and purification methods are employed to obtain relatively pure 1-chloronaphthalene.

1-Chloronaphthalene has found some industrial applications. Historically, it has been used as a dielectric fluid, a component in certain lubricants, and as an intermediate in the synthesis of other chemicals. Its physical properties, such as its high boiling point and electrical insulating capabilities, made it suitable for these purposes. However, due to environmental and health concerns associated with chlorinated organic compounds, its use has declined significantly, and many applications have been replaced by safer alternatives. Research has also explored its potential as a solvent and in specific chemical reactions.
