Abstract
Procedure for obtaining monopersulfuric acid consisting essentially of starting, as a first matter, of persulphuric acid or any of its water-soluble salts, and treating said raw material, with concentrated sulfuric acid and in excess, adding slowly and cooling the solution at 0º c. And maintaining a low temperature during the reaction period, after which the product of the reaction is left at rest for three to five days, which results in the transformation of the persulphuric acid into monopersulfuric acid, which is present in solution in an acidic environment and in a completely stable form, with concentrations of 18 to 20%.
