Product 1

HCID 24412Potassium Persulfate

Procedure

The ammonium persulfate in the form of crystal thus obtained is re-dissolved in the next step, and is transferred to the step of reaction with sodium hydroxide or potassium hydroxide. In the aforesaid reaction step, a solution containing sodium persulfate or potassium persulfate is produced, then is concentrated and separated by vacuum crystallization, centrifugal filtration or the like and is subsequently taken out as a crystal. As stated hereinbefore, the process for producing sodium persulfate or potassium persulfate by the reaction of ammonium persulfate and sodium hydroxide or potassium hydroxide necessitates quite a long production steps and a number of steps and moreover, lowers the yield of the objective sodium persulfate or potassium persulfate based on the ammonium persulfate, thereby making itself far from economically advantageous.
