Abstract
Dialkanesulfonyl peroxide (RSO.sub.2 --O--O--O.sub.2 SR) is prepared in a continuous process by electrolyzing the corresponding alkanesulfonic acid at an elevated temperature (to keep the peroxide product in solution) in a continuous-flow electrolysis cell, removing the solution from the electrolytic cell, cooling the solution to precipitate the peroxide product, and recycling the supernatant alkanesulfonic acid back to the cell.
