Abstract:
A method of preparing a hydroxylammonium salt, comprising the steps of:(A) providing an electrochemical cell comprising an anode, a cathode, and a divider positioned between the anode and the cathode, to define a catholyte compartment between the cathode and the divider and an anolyte compartment between the anode and the divider;(B) charging the catholyte compartment with a first solution comprising a nitrogen containing compound and a mediator and the anolyte compartment with a second solution comprising an ionic compound;(C) passing a current through the electrochemical cell to produce a hydroxylammonium salt in the catholyte compartment; and(D) recovering the hydroxylammonium salt from the catholyte compartment.
