Documented Uses

• Used as an immersion liquid in the microscopic determination of the refractive index of crystals; Has also been used to make plasticizers and as a solvent for oils, fats, and DDT; Chlorinated naphthalenes have not been manufactured in the US since 1977; [HSDB]
• Used as oil additive (clean sludge and deposits); with Halowax 1000 in textile dyeing; [HSDB] See CHLORINATED NAPHTHALENES.
• ... Except in special cases, chlorinated naphthalenes are no longer used in capacitors or electric cable coverings. Their use as lubricants has also been largely discontinued. Practice in individual countries varies, however. In the USA, for example, chlorinated naphthalenes are no longer used as wood preservatives. /Chlorinated naphthalenes/
• As raw material for dye production; oil additive to clear sludge and petroleum deposits in engines.
• Electrical insulation and fire-resisting materials; impregnants; sealing compounds; crankcase additive; ingredient in penetrating oils; plasticizer; protective coatings. /Halowax/
• Monochloronaphthalenes and mixtures of mono- and dichloronaphthalenes have been used for chemical-resistant gauge fluids and instrument seals, as heat exchange fluids, as high boiling speciality solvents, for color dispersions, as engine crankcase additives, and as ingredients in motor tune-up compounds.
