Quick Summary

Chlorination is the process of adding chlorine to a molecule. Chlorine itself is a toxic, greenish-yellow gas that is a halogen element. This process often involves a substitution reaction, where an atom or group in a molecule is replaced by chlorine. For example, in the synthesis of chloromethane, methanol reacts with hydrogen chloride. Chlorination can also occur through the reaction of chlorine with alkenes or alkanes. This chemical process is fundamental in producing various organic compounds, including plastics, solvents, and refrigerants.1234

dichlorobenzene
…dichlorobenzenes is produced by the chlorination of chlorobenzene or by the dichlorination of benzene in the presence of iron(III) chloride. The 1,4- isomer is the most easily isolated of the dichlorobenzenes and was first described in 1864; the 1,2- and 1,3- isomers were not recognized until 1875.
