The invention relates to a process for the preparation of a peracid, perester or diacylperoxide and is characterized in that a mixed anhydride of formula: R1[C(O)OC(O)OR2]n or [R3C(O)OC(O)O]¿pR?4 is contacted with a hydroperoxide of formula: R5[OOH]m in the presence of a base, wherein R1 represents a mono-, di-, tri- or tetravalent C¿1?-C19 hydrocarbon group, optionally containing one or more hetero atoms, n is 1-4, R?2¿ represents a C¿1?-C20 hydrocarbon group, optionally containing one or more hetero atoms, R?3¿ represents a C¿1?-C19 hydrocarbon group, optionally containing one or more hetero atoms, R?4¿ represents a di-, tri- or tetravalent C¿1?-C20 hydrocarbon group, optionally containing one or more hetero atoms, p is 2-4, R?5¿ represents hydrogen or a mono- or divalent C¿3?-C18 tertiary alkyl or C2-C20 acyl group, in which the tertiary alkyl or acyl group may optionally contain one or more hetero atoms, m is 1 or 2, and if R?5¿ represents hydrogen, m is 1, provided that if the hydroperoxide is an α,α-dihydroperoxyperoxide, the reaction is not carried out in an inert two-phase solvent system comprising a polar solvent and an polar solvent. The invention also relates to a hydroxyperacid, hydroxyperester, and hydroxydiacylperoxide obtainable by said process and the use of said hydroxyperoxides.
