1,2-Dichlorobenzene Usage And Synthesis
Chemical Properties colourless liquid
Chemical Properties There are three isomeric forms of dichlorobenzene (DCB): m-DCB is a flammable liquid and vapor.
Chemical Properties 1,2-Dichlorobenzene (DCB, o-Dichlorobenzene, ODB, Orthodichlorobenzene), C6H4Cl2, is a colorless to pale yellow liquid with a pleasant aromatic odor. It is a combustible liquid and can form explosive mixtures with air at or above 151°F. Combustion and thermal decomposition products include hydrogen chloride gas, phosgene and chloro-carbons. Its flammable (explosive) limits are as follows: Lower 2.2%, Upper 9.2%.
