Extraction and presentation
2-methylnaphthalene can be obtained by isomerizing 1-methylnaphthalene or from a methylnaphthalene fraction of coal tar that contains 1.5% 2-methylnaphthalene. Around 1500 tons are produced worldwide each year.
2-methylnaphthalene is a flammable white solid with an aromatic odor that is practically insoluble in water.
2-methylnaphthalene is used as a mixture with 1-methylnaphthalene as a solvent and heat transfer oil. It also serves as a starting material for the production of menadione and naphthalene-2,6-dicarboxylic acid .
In August 2010, Kellogg’s recalled 28 million packets of muesli from stores because some of them were contaminated with 2-methylnaphthalene. In 2012, Kellogg's had to recall nearly 3 million cereals again.
