Definitions

  • This invention relates to a process for the manufacture of acid solutions of ammonium persulphate by electrolysis using electrolytic cells having a-stationary catholyte. Such solutions can be hydrolysed and distilled to yield hydrogen peroxide or treated to give ammonium persulphate crystals.
  • the present invention provides a process for the manufacture of acid solutions of ammonium persulphate by the electrolysis of acid solutions of ammonium sulphate using an electrolytic cell having a stationary catholyte 'whereinthe catholyte i maintained acid in reaction throughout the electrolysis and wherein the cathode is surrounded by a closely spaced porous ceramic diaphragm.
  • Fig. 1 shows a longitudinal sectional view of the cell and Fig. 2 shows a plan view of part of the cell.
  • the cell I contains a plurality of cathodes 2 screwed into a bar 3 of the cell, each cathode being surrounded by a closely fitting porous ceramic diaphragm 4.
  • the anodes 5 are disposed in the anolyte 6 the level of which is indicated at I.
  • the anolyte solution is led into the cell I through an inlet pipe 8 and discharges through an overflow pipe 9.
  • A. preferred embodiment of this invention for the manufacture of acid solutions of ammonium persulphate comprises electrolysing and acid soof the diaphragm is between 10 and 40. mls. per
  • the acid solution of ammonium persulphate obtained may be hydrolysed and distilled to give hydrogen peroxide or it may be converted into ammonium persulphate crystals in ways well known to those skilled in the art.
