Fluorocarbon

Name:
Fluorocarbon
Detailed information:
Any of a number of organic compounds analogous to hydrocarbons in which the hydrogen atoms have been replaced by fluorine. The term is loosely used to include fluorocarbons that contain chlorine; these should properly be called chlorofluorocarbons or fluorocarbon chloride, since they deplete the ozone layer of the upper atmosphere.See Chlorofluorocarbon.

Properties:

Fluorocarbons are chemically inert, nonflammable, and stable to heat up to 260–315C. They are denser and more volatile than the corresponding hydrocarbons and have low refractive indices, low dielectric constants, low solubilities, low surface tensions, and viscosities comparable to hydrocarbons. Some are compressed gases and others are liquids.

Hazard:

Nonflammable; reacts violently with reactive substances, e.g., barium, sodium, and potassium.

Use:

Refrigerants, solvents, blowing agents, fire extinguishment, lubricants and hydraulic fluids, flotation and damping fluids, dielectric, plastics, electrical insulation, wax coatings for alkali cleaning tanks, air- conditioning. Note: Many of these compounds are designated by a number system preceded by the word refrigerant, propellant, fluorocarbon or by a TM (“Freon,” “Ucon,” “Genetron”).They are cross-referenced in this book as follows:11. See Trichlorofluoromethane.12. See Dichlorodifluoromethane.13. See Chlorotrifluoromethane.14. See Tetrafluoromethane.21. See dichlorofluoromethane.22. See chlorofluoromethane.23. See Fluoroform.113. See 1,1,2-trichloro-1,2,2-trifluoroethane.114. See 1,2-dichloro-1,1,2,2-tetrafluoroethane.115. See Chloropentafluoroethane.116. See Hexafluoroethane.
