Uses and applications

What the substance is used for, by industry and function

Solvent for camphor, sulfur & iodine, in paint thinners, as paint remover when mixed with decalin or white spirit, as insecticide for clothes moth, as substitute for turpentine & petrol in germany.

Solvent for naphthalene, fats, resins, oils, waxes, used instead of turpentine in lacquers, shoe polishes, floor waxes, degreasing agent.

In plant pathology, tetralin has been successful in total destruction of crown gall and olive knot neoplasms.

A combination of 31% tetrahydronaphthalene and 0.03% cupric oleate (cuprex) is promoted as a pediculicide and miticide, but its true efficacy remains to be determined.

How it is made

By catalytic hydrogenation of purified naphthalene.

Formed during acidic, catalytic hydrocracking of phenanthrene.

Isolated from middle fraction of coal oil.
