Abstract

Disposal of chlorinated organic prods. is effected by (a) treating the prods. with a sulphonating or nitrating agent; and (b) oxidising the prods. from (a) with an aq. soln. of H2O2 in the presence of Fe(II) ions and optionally one or more ions of Cu(II), Ti(IV), Mn(II), Co(II), Ni(II), V(IV) and Mo(IV). The sulphonating agent is pref. H2SO4 (pref. used as a 70-99 wt.% conc. aq. soln.) or oleum. The nitrating agent is HNO3 (used as 50-99 wt.% conc. aq. soln.) mixed with a strong mineral acid (pref. 70-99 wt.% concn. H2SO4). The molar ratio of mineral acid HNO3 is 0.5-5.
