" F R E O N - 1 1 2 " (CCIoFCCUF). Used as a solvent, in heat exchange and virus purification.
Freon FiuorocanDons have 15 dmereni B.P.s one could be right lor your process! " F r e o n " fluorocarbons are an interesting family of 15 commercial compounds. Boiling points vary all the way from -198.4 9 F to + 199.0°F.—yet basic properties are similar t h r o u g h o u t t h e group. These properties are: 1. Thermal stabil ity. 2. Non-flammability. 3. Very low toxicity· 4. Chemical inertness. 5. Low surface tension. 6. Low viscosity. 7. Selective solvency. 8. l m mjscibility with water. 9. Outstanding dielectric properties. tc Freon" fluorocarbons are now used widely as refrigerants, aerosol propellents, foam blow ing agents, polymer intermediates and selective solvents. Their unique combination of proper ties should putthem into many new uses as well. For instance, the low-boiling ones look inter esting as cryogenic reaction and heat-transfer media, in environmental testing, and in low-tem perature medical preparations. Their selective soLvency and water immiscibility suggest use as organic separation and extraction agents. "Freon-C31.8" is FDA-accepted so it can be used in contact with food, as in a defatting agent for meat. And there are many possibilities for combinations of " F r e o n " fluorocarbons with themselves or other chemicals. We'll help you develop any ideas you have!
