Description

General description

Tetralin is a bicyclic molecule composed of an aromatic moiety and an alicyclic moiety that share two carbon atoms in common. It is used as a hydrogen-donor solvent in coal liquefaction. Tetralin is also used to synthesize agricultural chemicals. Additionally, it is used as a degreaser and solvent for fats, resins, and waxes and as a substitute for turpentine in paints, lacquers, and shoe polishes.

Application

1,2,3,4-Tetrahydronaphthalene is used as a:

• Hydrogen-donor solvent in the decarboxylation of oleic acid to produce diesel fuel hydrocarbons.
• Hydrogen source for the hydrogenation of lignin-derived phenolic compounds.
