1methylnaphthalene

1-Methylnaphthalene is an organic compound with the chemical formula C11H10. It is a substituted naphthalene, meaning it consists of a naphthalene molecule with a methyl group attached. Specifically, the methyl group is located at the 1-position of the naphthalene ring system. It is a colorless to pale yellow liquid with a distinct odor. 1-Methylnaphthalene is one of the isomers of methylnaphthalene, with the other being 2-methylnaphthalene.

This compound is found in coal tar, which is a byproduct of the destructive distillation of coal. It is also present in petroleum fractions. Due to its presence in these complex mixtures, its separation and purification are important for various applications. 1-Methylnaphthalene can be synthesized through various organic reactions, including Friedel-Crafts alkylation of naphthalene.

Industrially, 1-methylnaphthalene has found use as a solvent for certain resins and dyes. It has also been investigated as a component in jet fuels and as a precursor in the synthesis of other organic chemicals. Its properties, such as its relatively high boiling point and solvency, make it suitable for these purposes. Environmental considerations regarding its persistence and potential toxicity are also subjects of study.
