halogenated compounds

The mutagenicity activity of halogenated compounds found in chlorinated drinking water.

This detector is particularly sensitive to halogenated compounds.

They transformed pure oil into several halogenated compounds, which were further transformed in other reactions.

These anions may react with various electrophiles especially with halogenated compounds.

However, contrary to cprA5, these three genes were also expressed in the absence of halogenated compounds in the culture medium.

Preparations of several halogenated compounds including pharmaceutically interesting enol lactones are reported.

Toxic activity of seventeen industrial solvents and halogenated compounds on human lymphocytes cultured in vitro.

High concentrations of halogenated compounds may reduce the biofilter's efficiency and even partially destroy the microbial flora.

Bleaching with hypochlorite generates halogenated compounds in side reactions; chloroform is the main byproduct.

These are able to destroy organic contaminates which are ordinarily difficult to remove, such as aromatic or halogenated compounds.

An ECD has a limited dynamic range and finds its greatest application in analysis of halogenated compounds.

The bacteria Nitrosomonas europaea can degrade a variety of halogenated compounds including trichloroethylene .

Halorespiration or dehalorespiration is the use of halogenated compounds as terminal electron acceptors in anaerobic respiration.

The decomposition products of halogenated compounds are highly corrosive, the occurrence of corona discharge should therefore be prevented.

Its variety of coordination geometries enable tert-butylphosphaacetylene to participate in several types of reactions, including 1,2-additions of halogenated compounds.

Often involve highly halogenated compounds (eg Cl, F, Br)

The species Nitrosomonas europaea has been identified as also being able to degrade a variety of halogenated compounds including trichloroethylene, benzene, and vinyl chloride.

The electron capture detector is used for detecting electron-absorbing components (high electronegativity) such as halogenated compounds in the output stream of a gas chromatograph.

Many synthetic organic compounds such as plastic polymers, and a few natural ones, contain halogen atoms; they are known as halogenated compounds or organohalogens.

Zirconium hydrides are soluble in hydrofluoric acid or alcohol; they react violently with water, acids, oxidizers or halogenated compounds.

Background Studies have shown that anthropogenic releases of certain halogenated compounds damage the ozone layer, thereby allowing for higher levels of ultraviolet radiation to reach the earth’s surface.

It is attacked by halogens and strong Bronsted and Lewis acids as well as some halogenated compounds and aliphatic hydrocarbons at high temperatures.
