1,3-Dichlorobenzene (also known as meta-dichlorobenzene) is an aryl chloride and isomer of dichlorobenzene with the formula C 6 H 4 Cl 2.It is the least common of the three isomers of dichlorobenzene, and it is a colorless liquid that is insoluble in water.
1,2-Dichlorobenzene or ortho-dichlorobenzene; 1,3-Dichlorobenzene or meta-dichlorobenzene; 1,4-Dichlorobenzene or para-dichlorobenzene. All three isomers are colorless chlorobenzenes with the formula C 6 H 4 Cl 2. They differ structurally based on where the two chlorine atoms are attached to the ring.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

1,3,5-Trichlorobenzene is an organochlorine compound. It is one of the three isomers of trichlorobenzene . Being more symmetrical than the other isomers, it exists as colourless crystals whereas the other isomers are liquids at room temperature.

However, because it has only been found at 97 out of 1,177 NPL hazardous waste sites, it is not considered a widespread environmental contaminant. The bacterium Rhodococcus phenolicus degrades chlorobenzene, dichlorobenzene and phenol as sole carbon sources. [12]
p-DCB is produced by chlorination of benzene using ferric chloride as a catalyst: . C 6 H 6 + 2 Cl 2 → C 6 H 4 Cl 2 + 2 HCl. The chief impurity is the 1,2 isomer.The compound can be purified by fractional crystallization, taking advantage of its relatively high melting point of 53.5 °C; the isomeric dichlorobenzenes and chlorobenzene melt well below room temperature.
