Sulfuric Acid → Sulfuric Acid

Participants

Reaction Steps

Solutions containing Caro's acid and sulfuric acid can be used in the method of DE 10 80 083 which were obtained either by means of electrolysis of a sulfuric acid with a content of preferably 35% to 50% by weight, with subsequent hydrolysis of the peroxodisulfuric acid formed or by means of the reaction of 50% to 88% by weight aqueous hydrogen peroxide with concentrated or fuming sulfuric acid (oleum). In order to prepare sodium peroxymonosulfate, such H2SO5 /H2SO4 solutions are neutralized with a soda solution up to pH 2.9, freed of the precipitated Glauber salt and subsequently dried.
