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.
Contents
Properties
Chemical
The reaction of elemental bromine with tetralin will give dry hydrogen bromide gas:
- C10H12 + 4 Br2 → C10H8Br4 + 4 HBr ↑
Physical
Tetralin is a colorless viscous liquid, with a faint naphthalene-like smell. It is insoluble in water, but miscible with many organic solvents.
Availability
Tetralin can be purchased from chemical suppliers.
Preparation
There are several ways to prepare Tetralin.
The most convenient route involves the partial hydrogenation of naphthalene with a platinum catalyst. Small amounts of side products, such as decalin are also produced.
Birch reduction of naphthalene is another route, however the reaction is not selective and is a dangerous method.
Projects
Handling
Safety
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.
Storage
In closed bottles.
Disposal
Should be mixed with a more flammable solvent and burned.
