Polychloroaromatic Compounds PDF

The chlorination of aromatic and heteroaromatic compounds is one of the oldest and also one of the most important reactions since it heralded the rise of the heavy organic chemicals industry. Reports of polychlorobenzenes and polychloropyridines date back well into the last century and it is of historical interest that Kekule was probably the first to have prepared pentachloropyridine. Yet, in spite of the ancient lineage and the practical as well as theoretical significance of polychloroaromatics, there has existed so far no review exclusively devoted to their chemistry. Three inter­ national symposia on polychloro-chemistry since 1968, in which polychloroaromatics figured prominently in discussions amongst chemists and biologists, are evidence for the growing importance of this subject. Information on the chemistry and uses of the numerous polychloroaromatic compounds has remained buried largely in the journal and patent literature and only occasionally receives sparse and incidental treatment in an article primarily dealing with a specific ring system.

Preparation of highly chlorinated pyridines - The … 28.07.1981 · Highly chlorinated pyridines are prepared by reacting 2,6-dichloropyridine with chlorine at temperatures of from about 150° to about 300° C. in the presence of an aluminum, iron or silica oxide catalyst and under sufficient pressure to maintain the 2,6-dichloropyridine reactant as a liquid.

in 77/23 dioxan/water at 92°, showed these compounds to have similar reactivities, within a factor of 3 or 4, but their reactivities were several orders of magnitude greater than that of pentafluorobenzene. The order of reactivity was found to be perfluoro-t-butylbenzene > perfluoroethylbenzene > perfluoroisopropylbenzene > perfluorotoluene. From these results it was concluded that the

Model compound studies which were previously done for impurities and environmental residues of chlorophenols and for wastes of chlorination processes were extended to the impurities and pyrolysis products of polychlorinated biphenyls (PCBs). Model compounds were commercial products or synthesized and their structures proven by spectroscopic
