1,3-Dichlorobenzene is an organic compound with the formula C6H4Cl2. It is the least common of the three isomers of dichlorobenzene, it is a colorless liquid that is insoluble in water. It is produced as a minor byproduct of the chlorination of benzene, but can also be prepared in a directed manner by the Sandmeyer reaction of 3-chloroaniline. It also arises from the isomerization of the other dichlorobenzenes at high temperature. Meta-dichlorobenzene is an important organic chemical raw material. In pesticides, it is not only the raw material of insecticide trichlorocidal ester, but also used to synthesize its intermediate 1-(3, 4-dichlorophenyl)-2, 2, 2-chemicalbook trichloroethanol. In addition, it can also synthesize another important pesticide intermediate, o-phenylenediamine. It is also used as a solvent for dye, medicine, resin, rubber and other operations, or as a rust remover, degreasing agent, etc.
