Information @ a Glance

• The chlorination of methane proceeds through a radical mechanism. Like most radical mechanisms there are three steps: initiation, propagation and termination.

• The chlorination of methane does not necessarily stop after one chlorination. It may actually be very hard to get a monosubstituted chloromethane. Instead di-, tri- and even tetra-chloromethanes are formed.

• Methylene dichloride , chloroform , and carbon tetrachloride are three basic products of methane chlorination and are produced by high temperature gas phase chlorination of methane or methyl chloride.

• Chloroform is also known as trichloromethane or methyltrichloride. It is a colorless liquid with a pleasant, nonirritating odor and a slightly sweet taste. Most of the chloroform found in the environment comes from industry.

• Chloromethane is used almost entirely as a chemical intermediate to make other chloromethanes, silicone intermediates, pesticides, quaternary amines and surfactants, and as a methylation reactant for various other processes. It is also used as a solvent for production of butyl rubber.

• Methane chlorination reactions proceed by a multi-step series of exothermic reactions which are stabilized in a con ned jet con guration where reactants are typically introduced at temperatures well below the minimum activation temperature.

• The Conventional method of producing chlorinated methanes involves the reaction of methane with chlorine gas. For each substitution of a chlorine atom into the methane molecule, one molecule of hydrogen chloride is produced.

• Chloromethane (CH3CI), dichloromethane (CH2C12), tricloromethane (CHC13), and tetrachloromethane (CC14) are produced on a scale of approximately 2 million tons per year and used as intermediates in chemical synthesis and as industrial solvents.

• Chloromethanes can be divided into two categories; either the lower- or higher chlorinated methanes, based on the distinct behaviour patterns in their biodegradability.

• Demand for methylene chloride on the export market had been steadily increasing since January, producers said, which had pushed prices to levels some had not previously expected.

• Globally, about 90-95% of the chloroform is used as a precursor for HCFC-22, which is used in refrigerants and fluoropolymers such as polytetrafluoro-ethylene (PTFE).

• Carbon tetrachloride is used as a chemical intermediate and as a feedstock in the production of chlorofluorocarbons, such as the Freons dichlorodifluoromethane and trichlorofluromethane , which are used primarily as refrigerants.
