Freon

Freon is a colorless gas at room temperature or volatile liquid, slightly aroma, low toxicity, stable chemical properties. One of the most important is dichlorodifluoromethane CCl2F2 (F - 12). Dichlorodifluoromethane for colorless gas under normal temperature atmospheric pressure; Melting point - 158 degrees Celsius, the boiling point 29.8 degrees Celsius, density 1.486 g/cm (30 degrees Celsius); Slightly soluble in water, soluble in ethanol, ethyl ether; Do not reaction with acid, alkali. Dichlorodifluoromethane can be made of carbon tetrachloride and anhydrous hydrogen fluoride in the reaction system in the presence of catalyst, the reaction product is dichlorodifluoromethane, and CCl3F and CClF3 will CCl2F2 separated by fractionation.
