Tetralin (IUPAC name 1,2,3,4-tetrahydronaphthalene) is an organic compound, a hydrocarbon having the chemical formula C10H12. It is similar to naphthalene in structure, except one ring is saturated.
- C10H12 + 4 Br2 → C10H8Br4 + 4 HBr ↑
Tetralin is a colorless viscous liquid, with a faint naphthalene-like smell. It is insoluble in water, but miscible with many organic solvents, like alcohols.
Tetralin can be purchased from chemical suppliers.
There are several ways to prepare Tetralin.
Birch reduction of naphthalene is another route, however the reaction is not selective. Birch reduction is also a dangerous and time-consuming method.
Tetralin is irritant and should be handled with care. With a flash point of 77 °C, it is not very flammable and unless heated prior, it doesn't pose a fire hazard.
In closed air-tight bottles. Since it may form peroxides in contact with air, it's best to test it for peroxides every few months.
Should be mixed with a more flammable solvent and burned.
