Haloorganic compound

The Curie Point flush evaporation-pyrolysis gas chromatography-mass spectrometric method [27] described in section 2.2.1.2 for the analysis of aliphatic hydrocarbons in soils has also been applied to the determination of haloorganic compounds such as di- and trichlorobenzenes.

A long series on the kinetics and mechanism of the unimolecular heterolysis of commercial haloorganic compounds has continued in a study of the effect of bromide salts and lithium perchlorate on the ionization rate of benzhydryl bromide in y-butyrolactone and acetone.122 The verdazyl indicator method was applied. The nature of special and normal salt effects has also been discussed.123... 

Two previous reviews on radiolysis of haloorganic compounds were published in this series n 2. Consequently, this review is only for the period starting in 1983.

A class of peroxidases specializes in the (per)oxidation of halides (d , Br , T but not FO, thus creating reactive halogenating species (such as hypohalite), which in turn form haloorganic compounds [1320, 1321]. These reactions are described in Sect. 2.7.1. 

Inmost instances, a haloorganic subject to either SN2 displacement reaction or SN1 substitution is heated at reflux with the trivalent phosphorus ester with the concomitant formation of the valence-expanded organophosphorus compound and haloorganic by-product, as illustrated with an example in Equation 3.1. 

ABSTRACT Photooxidation of many organic compounds (e.g., haloorganics, surfactants, pesticides, etc.) dissolved in aqueous systems over illuminated semiconductor materials (e.g., Ti02> leads in almost all cases to quantitative formation of carbon dioxide and, eventually, of inorganic acids (e.g., HCl from chlorinated compounds). The possible application in the treatment of both waste waters and drinking water is illustrated. 

Naturally occurring haloorganics have long attracted attention, owing to their medicinal properties. The synthesis of haloaromatic compounds typically includes electrophilic attack of activated aromatic rings.
