Most people who produce ammonium persulfate would do so by electrolysis 
at cold temperatures with platinum anode at high current density in a 
solution of high concentration of ammonium sulfate. The solubility of 
persulfate is significantly lower than sulfate and allows separation. 
High anode current densities increase persulfate/oxygen ratio since some 
water electrolysis is unavoidable.

I don't think any the chemical reactions you describe would make 
persulfates.
