Overview

1,3-Dichlorobenzene is a thermodynamically favoured isomer of 1,4-dichlorobenzene. The heat capacity at constant pressure and density of 1,3-dichlorobenzene was measured in the temperature range from (283.15 to 353.15)K.

Application
1,3-Dichlorobenzene was used to study the effect of solvent vapor pressure on the vertical nanowire of C60 molecules. 1,3-Dichlorobenzene, a chlorinated aromatic hydrocarbon, can be detected in environmental samples using an advanced Fourier transform infrared spectroscopy-attenuated total reflectance (FTIR-ATR) sensor.
