1,2-Dichlorobenzene, or ortho-dichlorobenzene (ODCB), is an organic compound with the formula C6H4Cl2. This colourless liquid is poorly soluble in water but miscible with most organic solvents. It is a derivative of benzene, consisting of two adjacent chlorine centers.
Production and uses
1,2-Dichlorobenzene is obtained as a side-product of the production of chlorobenzene:
- C6H5Cl + Cl2 → C6H4Cl2 + HCl
The reaction also affords the 1,4- and small amounts of the 1,3-isomer.
It is mainly used as a precursor to 1,2-dichloro-4-nitrobenzene, an intermediate in the synthesis of agrochemicals.[2] In terms of niche applications, 1,2-dichlorobenzene is a versatile, high-boiling solvent. It is a preferred solvent for dissolving and working with fullerenes. It is an insecticide for termites and locust borers.[citation needed]
1,2-Dichlorobenzene is also used in softening and removing carbon-based contamination on metal surfaces.[3]
