Formation of dibenzodioxins and other condensation products from chlorinated phenols and derivatives.
Introduction Chlorodioxins can be formed in a two-step condensation reaction from ortho-substituted chlorophenoxy radicals or anions (1-3). The first route is of significance only where strongly oxidizing conditions exist such as a reaction of chlorine with pentachlorophenol at elevated temperature. For the second route we have investigated the condensation of alkali metal salts of chlorinated ...
متن کاملChlorinated dibenzodioxins and dibenzofurans.
The problems and universal concern about chlorinated dibenzodioxin and dibenzofuran compounds were brought to the forefront by the scientific community during the National Institute of Environmental Health Sciences' (NIEHS) Conference on this subject which was held at Research Triangle Park, North Carolina, April 2 and 3, 1973. This idea for this literature collection emanated from that scienti...
متن کاملChlorinated dibenzodioxins and pentachlorophenol.
Introduction Pentachlorophenol is a registered anti-microbial agent whose principal use is for the preservation of wood. Typical commercial pentachlorophenol contains a variety of substances which are considered to be "in-active" from the aspect of antimicrobial efficacy. Consequently, pentachlorophenol is sold as an antimicrobial agent with 95%o active ingredients and 5%o "inert" ingredients. ...
متن کاملPerspective on CHLORINATED DIBENZODIOXINS And DIBENZOFURANS
Background: Angiogenesis is a fundamental process that allows tumor growth by providing nutrients and oxygen to the tumor cells. Beyond the oxygen diffusion limit from a capillary blood vessel, tumor cells become apoptotic. Angiogenesis results from a balance of proand antiangiogenic stimuli. Endogenous inhibitors regulate enzyme activities that promote angiogenesis. Tumor cells may express pro...
