How can you use this property of FREON fluorocarbons? c HEMIC AI INERTNESS is a property of the entire family of FREON fluorocarbonseach of which has a specific boiling point lying between +199.0° and 198.4°F! So whatever the operating temperature of your process, there's a FREON that might be valuable as a liquid or gaseous organic reaction medium, cleaning solvent or purifying agent. There are other properties also common to all FREON compounds regardless of boiling point: 1. High thermal stability 6. Outstanding dielectric properties Selective solvency 7. Low surface tension 3. Jmmiscibility with water Low viscosity 4. Nonflammability High density 5. Low toxicity Have you an idea where any of this unique family of chemicals could be used? We'll help you develop it if you do! Clue: FREON fluorocarbons are used today as refrigerants, aerosol propellents, foam blowing agents, solvents, dielectrics, heat-transfer media, polymer intermediates and aerospace products.
