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 estrogenicity of o-, m-, and p-dichlorobenzene (DCB) was evaluated with a yeast estrogen screen (YES) and zebrafish (Danio rerio) vitellogenin (VTG) assays. With the YES, p-DCB and m-DCB were found to be estrogenic in a concentration-responsive manner. The relative

Studies were conducted to examine acute hepatic and renal toxicity of dichlorobenzene (DCB) structural isomers. Male Fischer 344 (F344) rats were injected with 2, 3 or 4 mmol kg-1 of 1,2-DCB, 1,3-DCB or 1,4-DCB (o-, m-, p-). Pair-fed control (PFC)
