[8] At 400500C, a free radical halogenation occurs, converting these precursors to progressively more chlorinated compounds: Chloroform undergoes further chlorination to yield carbon tetrachloride (CCl4): The output of this process is a mixture of the four chloromethanes: chloromethane, dichloromethane, trichloromethane (chloroform), and tetrachloromethane (carbon tetrachloride). It is also found in waste water from sewage treatment plants and drinking water to which chlorine has been added.
