General description

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 is suitable as carbon and energy supplement for the growth of gram-negative, peritrichously flagellated rod, tentatively identified as an Alcaligenes sp.

A gram-negative, peritrichously flagellated rod, tentatively identified as an Alcaligenes sp., was isolated from a mixture of soil and water samples by using 1,3-dichlorobenzene as the sole carbon and energy source. During growth on 1,3-dichlorobenzene, almost stoichiometric amounts of chloride

The isomerisation reaction of 1,4-dichlorobenzene leading to the thermodynamically favoured and technically desired 1,3-dichlorobenzene has been studied comparing highly acidic chloroaluminate melts with organic imidazolium and alkali metal ions. Interestingly, the inorganic melts show much higher reactivity and full recyclability

The FT-IR and FT-Raman vibrational spectra of 1,3-dichlorobenzene (1,3-DCB) have been recorded using Bruker IFS 66 V Spectrometer in the range 4000-100 cm(-1). A detailed vibrational spectral analysis has been carried out and assignments of the observed fundamental bands have

Enrichment cultures capable of reductively dechlorinating 1,2,4-trichlorodibenzo-p-dioxin (1,2,4-TrCDD) were shown to dechlorinate 1,2,3-trichlorobenzene (1,2,3-TrCB) to 1,3-dichlorobenzene. To test if this activity can be used to enrich for dioxin-dechlorinating bacteria, a two-liquid phase cultivation with 200 mM 1,2,3-TrCB dissolved in hexadecane
