Abstract

Disclosed is a continuous process for the production of bivalent metal peroxides, comprising the steps of introducing into an intensive mixing apparatus a solid, anhydrous or hydrated oxide or hydroxide of a bivalent metal; simultaneously introducing into the intensive mixing apparatus a solution of hydrogen peroxide, whereby the solid bivalent metal compound and the peroxide are intensively mixed and react to produce a reaction mixture containing bivalent metal peroxide; transporting the reaction mixture directly to a rapid dryer; and rapidly drying the reaction mixture to produce the bivalent metal peroxide in solid form.
