    Abstract: A method and apparatus for production of a high-concentration H2SO5 solution is presented. This high-concentration H2SO5 solution is useful for producing a stable, non-hygroscopic triple salt. The invention includes a single-stage reactor that includes a reservoir for holding an oxyacid solution and an inlet to the reservoir for receiving a peroxide solution. The peroxide solution is added such that a gradient of peroxide concentration forms in the oxyacid solution as a function of distance from the inlet, and less than all of the oxyacid solution reacts with the peroxide solution at a given time. A stirring mechanism slowly dissipates the gradient, so that any H2SO5 formed as a result of reaction between the peroxide and the oxyacid is stirred away from the high-peroxide concentration zone, thereby preventing the decomposition of H2SO5 by an equilibrium reaction. The temperature of the reservoir is maintained at less than or equal to 20 ° C.

    Abstract: Production of peroxomonosulphuric acid (Caro's acid) by reaction between concentrated hydrogen peroxide and sulphuric acid solutions can be impaired substantially when substoichiometric amounts of sulphuric acid are employed.The problem is ameliorated or removed by first forming a body of sulphuric acid-rich fluid (usually the smaller volume) and thereafter introducing into that body of fluid the hydrogen peroxide solution (usually the larger volume). The reaction mixture progressively becomes sulphuric acid-lean. The body of fluid is advantageously either concentrated sulphuric acid itself, or a premix formed by reaction between hydrogen peroxide and at least an equimolar amount of sulphuric acid. The process is particularly suitable for making Caro's acid when from 0.02 to 0.5 moles of sulphuric acid is employed per mole of hydrogen peroxide.

    Abstract: A process for obtaining monopersulphuric acid from hydrogen peroxide and sulphuric acid is disclosed. Hydrogen peroxide in the form of an aqueous solution with a concentration ranging from 35 to 100% and either concentrated sulphuric acid or fuming sulphuric acid are added simultaneously to a reaction vessel. The temperature of the reaction is maintained in the range -10*C to +80*C and the supply of the hydrogen peroxide and sulphuric acid to the reaction vessel is controlled so that the generation of the monoperoxysulphuric acid occurs when required and the quantity thereof produced is adjusted according to the quantity thereof required for reaction with another reactant, for example a pollutant, the concentration of the monoperoxysulphuric acid being substantially constant.
