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.

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.

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.

Storage

In closed bottles.

Disposal

Should be mixed with a more flammable solvent and burned.
