Abstract

1,132,617. Electrolytic reduction of aromatic nitro compounds. MILES LABORATORIES, Inc. Nov.22, 1966 [Dec.28, 1965], No.52299/66. Heading C7B. Aromatic nitro compounds e.g. nitrobenzene, for instance to form p-aminophenol bisulphate, or p-nitrophenol, are electrolytically reduced in the catholyte compartment of a cell having anolyte and catholyte separated by a diaphragm, the electrolyte in both anolyte and catholyte compartments comprising a substantially anhydrous mixture of acetic acid, at least 15% by weight of phosphoric and/or sulphuric acid and at least 1% by weight of sodium, potassium and/or ammonium acetate. The electrolyte preferably contains not more than 0À6% water. Electrolysis may be carried out using a voltage of 12-24 volts, current density of 1-10 Amps /sq.dm. of cathode area and a temperature of 52-80‹C. The process could be used to reduce 2, 4-dinitrotoluene or 2, 4, 6 trinitrotoluene. Diaphragms used may be of ceramic composition or of fritted Pyrex (regd. trade mark) glass having pore sizes between 0À1 and 1À4 microns, the anode may be carbon, platinum or lead and the cathode is preferably a Monel (regd. trade mark) metal screen. The cell may be heated in a steam bath prior to imposition of electric current.
