1-Methylnaphthalene synthesis

12synthesis methods
1-Methylnaphthalene is generally obtained from coal tar and petroleum oils. It is present in high-temperature coal tar in a concentration of 0.5% and is produced industrially from the methylnaphthalene fraction, which boils between 240 and 245 °C, by redistillation of the 2-methylnaphthalene filtrate following crystallization and separation of 2-methylnaphthalene.
