Abstract (en)
[origin: DE4001782A1] Oxidn. of organic pollutants contg. C, H, O and other elements in bound form is effected by reaction with NHO3 at 150-350 deg.C and 6-350 bar. The process is characterised in that water-insol. chlorinated hydrocarbons are oxidised (SiC). Pref. chlorinated dibenzodioxins and chlorinated dibenzofurnas are oxidised. In an examples, the substance oxidised is (a) a substance called chlophen, (b) 1,1-dichloroethane, or (c) chloranil contg. 15ppm octachlorodibenzo-p-dioxin and 1.2ppm octachlorodibenzofuran. The reaction is effected in an autoclave at 30-100 bar. The HNO3 is used in an amt. of 2-40 (esp. 2.5-7) g per g of pollutant. In an example, a mixt. of 30g chlophen and 910g of 20% HNO3 was heated in a Ta autoclave at 280 deg.C and 86 bar for 2 hr. After cooling, the prod. comprised a clear aq. phase and no oily phase. The aq. phase had a COD of 2.4g/l and contained no chlorinated dibenzo-p-dioxins or dibenzofurans. @(3pp Dwg.No.0/0).
