Recovery of actinides from actinide-aluminium alloys by chlorination: Part III - Chlorination with HCl(g)

Iron(III)-Catalyzed Chlorination of Activated Arenes.

A general and regioselective method for the chlorination of activated arenes has been developed. The transformation uses iron(III) triflimide as a powerful Lewis acid for the activation of N-chlorosuccinimide and the subsequent chlorination of a wide range of anisole, aniline, acetanilide, and phenol derivatives. The reaction was utilized for the late-stage mono- and dichlorination of a range o...

Salt Chlorination

Millions of people worldwide enjoy swimming pool activities every year. Traditionally, chlorine-containing chemicals have been used as the sanitizing agent. Some chlorine containing chemicals used include chlorine gas, sodium hypochlorite, calcium hypochlorite, lithium hypochlorite, and chlorinated isocyanurates. These chemicals enter the pool as a concentrated solution, or in the form of hypoc...

The Chlorination of Water

Chlorine is most readily available in the form of chloride of lime (bleaching powder), which can readily be obtained commercially. This, if freshly made, should contain 33 per cent, of free or active chlorine. It loses its efficacy on keeping, especially during hot weather; but this loss may be retarded by the addition of 25 per cent, of quicklime. Samples of the bleaching powder used should be...

Drinking Water Chlorination

Mutagenic by-products from chlorination of humic acid.

Chlorination of humic and fulvic acid results in the formation of direct-acting mutagenicity, detectable in the Salmonella/microsome assay (Ames test). This mutagenicity is being characterized as part of an overall effort aimed at evaluating potential health risks associated with the presence of mutagenic chemicals in drinking water. A number of chlorinated organic compounds, including several ...
