Phenol and HCl at 550 °C yield a large variety of chlorinated toxic compounds

摘要: During the past decade it has been shown conclusively that incineration of municipal and industrial wastes gives rise to emissions chlorinated dibenzodioxins dibenzofurans. However, mechanism by which these toxic compounds are formed not yet fully established. Some researchers believe presence organically bound chlorine is necessary, but others consider inorganic forms may also participate in process. We now report synthesis a large number environmental pollutants simple high-temperature experiment. The results show phenol HCl most likely precursors dibenzofurans combustion wastes. dependence reaction on concentration indicates way controlling formation during incineration.
