- Description
-
Chloroform is an organic compound with formula CHCl3. It is a colorless, sweet-smelling, dense liquid that is produced on a large scale as a precursor to PTFE and refrigerants, but the latter application is declining. It is one of the four chloromethanes and a trihalomethane.
In industry, chloroform is produced by heating a mixture of chlorine and either chloromethane or methane. At 400–500 °C, a free radical halogenation occurs, converting these precursors to progressively more chlorinated compounds:
CH4 + Cl2 → CH3Cl + HClCH3Cl + Cl2 → CH2Cl2 + HClCH2Cl2 + Cl2 → CHCl3 + HCl
Chloroform undergoes further chlorination to yield carbon tetrachloride (CCl4):CHCl3 + Cl2 → CCl4 + HCl
The output of this process is a mixture of the four chloromethanes (chloromethane, dichloromethane, chloroform, and carbon tetrachloride), which can then be separated by distillation.Source: Infogalactic, Chlorofom.
