CFC-11 is a colorless and transparent liquid at room temperature. It is non-flammable, inexplosive and low toxicity. It almost does not dissolve in water, but can dissolve in alcohol, ether, oil and many hydrocarbons. It is a refrigerant (0 ℃to 10℃ grade) applied in the air conditioners with centrifugal, cyclo compressors. It is also used as foaming agent for polyurethane foam.

Dichlorodifluoromethane, a colorless gas at room temperature, is a nontoxic, non-flammable, colorless, transparent liquid under the pressure created by itself. It has excellent thermal and chemical stabilities. It does not corrode metals except magnesium and magnesium alloy. It does not dissolve in water, but can easily dissolve in hydrocarbons, halohy drocarbons and certain solvents at any ratio. As a convenient and safe refrigreant, it can be used in various refrigeration systems with a temperature range from -60℃ to 10℃. It can also be used in these fields such as spice industry, medical treatments and plastic industry.
