This colourless liquid is poorly soluble in water but miscible with most organic solvents. 1,2-Dichlorobenzene contains two chlorine atoms connected to one benzene molecule. Most of the 1,2-DCB released into the environment is present as a vapor. 1,2-DCB can burn, but they do not burn easily. (L395, L553)"}]
