A process for the decomposition of peroxides (I), is effected by contacting a mixt. contg. (I) with oxide catalysts (II) of manganese, iron, nickel, cobalt, cerium, copper, molybdenum, vanadium and/or tungsten. Pref. (I) is hydrogen peroxide and/or an organic peroxide (II) contains manganese, iron, cerium, copper, vanadium and/or tungsten. The active mass of (II) consists of 1-100 wt.% manganese oxide and 99-0 wt.% of the oxides of iron, cerium, copper, vanadium and/or tungsten and is supported, pref. on cordierite, Al203, Ti02, silica gel and/or Zr02. The reaction is carried out at 0-80 deg.C and 0.01-50 bar. USE/ADVANTAGE - The process is useful for the controlled decomposition of peroxides. The process stream is contaminated with heavy metal ions to a lesser extent than prior art processes. |
