Unless modified by the presence of some other functional group, the physical properties of the aryl halides are much like those of the corresponding alkyl halides. Chlorobenzene and bromobenzene, for example, have boiling points very nearly the same as those of n-hexyl chloride and n-hexyl bromide like the alkyl halides, the aryl halides are insoluble in water and soluble in organic solvents.

The Stringfellow Superfund site in California poses analytical problems similar to those encountered with most waste sites across the United States and that may be best addressed via LC/MS based methods. Most of the organic compounds in aqueous leachates from this site cannot be characterized by GC/MS based methods. Analysis of Stringfellow bedrock groundwater shows that only 0.78% of the total dissolved organic materials are identifiable via purge and trap analysis (IQ). These are compounds such as acetone, trichloroethylene etc, whose physical properties are ideally suited for GC/MS separation and confirmation. Another 33% of the dissolved organic matter is characterized as "unknown", i.e., not extractable from the aqueous samples under any pH conditions and thus not analyzed via GC. Another 66% is 4-chlorobenzene sulfonic acid (PCBSA), an extremely polar and water soluble compound that is also not suitable for GC analysis. This compound, a waste product from DDT manufacture, is known to occur at this site because of the history of disposal of "sulfuric acid waste from industrial DDT synthesis.

Askarels. Askarels are mixtures of many isomer groups of PCBs and chlorobenzenes and may also contain phenoxypropene oxide or diepoxide. They are mainly used as transformer oils and are of many types, namely, A, B, C, D, E, F, and G. Physical properties of some askarels are shown in Tables 36.6 and 36.7.

Beilstein Handbook of Organic Chemistry. This reference (55) is one of the most significant collections of data in organic chemistry. The physical and chemical properties of organic compounds are tabulated in more than 500 fields. Most of these fields are searchable, and a sample of the record for chlorobenzene [108-90-7] is shown in Table 3.

A peer review panel was assembled for chlorobenzene. The panel consisted of the following members Dr. David Jollow, Professor in the Department of Pharmacology, Medical University of South Carolina, Charleston, South Carolina Dr. Henry Peters, Professor in the Department of Neurology, University of Wisconsin Clinical Science Center, Madison, Wisconsin Dr. Jay B. Silkworth, Research Scientist, Wadsworth Center Labs, New York Department of Health, Albany, New York Dr. Frank Lu, Private Toxicology Consultant. Miami, Florida Dr. James Pollard, Private Consultant, Las Vegas, Nevada. These experts collectively have knowledge of chlorobenzene s physical and chemical properties, toxicokinetics, key health end points, mechanisms of action, human and animal exposure, and quantification of risk to humans. All reviewers were selected in conformity with the conditions for peer review specified in Section 104(i)(13) of the Comprehensive Environmental Response, Compensation, and Liability Act, as amended.
