The dipole moment of nitrochlorobenzene, /x, = 2 78 D, is less than the dipole moment of nitrobenzene, /x, = 4 01 D, which indicates that the... 

Fluorinated aromatic compounds. Finger and Kruse found that an aromatic chlorine or bromine atom activated by an o- or p-nitro group is subject to nucleophilic displacement by fluoride ipn on reaction with potassium fluoride in solvents such as succinonitrile, dimethyl formamide, or dimethyl sulfoxide. Unpublished work at Olin Mathieson Chemical Corporation indicates that best results are obtained with dimethyl sulfoxide as solvent and with potassium fluoride that has been finely ground (<100 mesh) and dried in a vacuum oven at 100° for at least 4 hrs. prior to use. In a typical case a mixture of p-nitrochlorobenzene, potassium fluoride, and dimethyl sulfoxide is stirred under reflux at 180° for 8-9 hrs., the cooled mixture... 

An interesting investigation was made to indicate that PHB can form a new biodegradable adsorption material. Poly-3-hydroxybutyrate (PHB) was used as a new material to prepare a biomimetic adsorbent by a modified double emulsion solvent evaporation technique. The enrichment capacities of the adsorbent for toxic liposoluble organic compounds were evaluated by chlorobenzene (CB) and o-nitrochlorobenzene (u-NCB) with the adsorption isotherms, enrichment factor (EF) and enrichment kinetics. ...
