オクタクロロスチレン

説明Octachlorostyrene(OCS) is a persistent, highly bioaccumulative, and toxic halogenated aromatic compound. It is not commercially manufactured, but is reportedly an inadvertent by-product of processes that combine carbon and chlorine under elevated temperatures. Magnesium production, chloride solvent production, aluminum plasma etching, aluminum degassing with hexachloroethane, chlorination of titanium, waste incineration, and chloro-alkali production with graphite anodes process are considered to be candidate occupations that produce OCS. However, recent advances have been made in process technology and pollution prevention practices in some of these industries, such as largely eliminating the electrolytic manufacture of chlorine and aluminum degassing with hexachloroethane, both of which have likely resulted in reductions in known sources of OCS.

使用OCS is used in pesticide products to increase the effectiveness of the active ingredients, to make the product easier to apply, or to allow several active ingredients to mix in one solution.
