dichlorodifluoromethane usage and synthesis

chemical properties	colourless odourless gas
general description	a colorless gas having a faint ethereal odor. shipped as a liquid confined under its own vapor pressure. contact with the unconfined liquid can cause frostbite. both components are noncombustible. can asphyxiate by the displacement of air. exposure of the closed container to prolonged heat or fire can cause dichlorodifluoromethane to rupture violently and rocket.
air & water reactions	the liquefied gas poured into water can be violently explosive. this is due to the phase transition from superheated liquid to vapor.
reactivity profile	the reaction of aluminum with various halogenated hydrocarbons produces a self-sustaining reaction with sufficient heat to melt aluminum pieces, examples of other halogenated hydrocarbons are fluorotrichloromethane, dichlorodifluoromethane, chlorodifluoromethane, tetrafluoromethane. the vigor of the reaction appears to be dependent on the combined degree of fluorination and the vapor pressure, [chem. eng. news 39(27):44(1961)].
health hazard	inhalation: some narcosis when 10% in air is breathed.
