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 R &lsqb;C(O)OC(O)OR &rsqb; or &lsqb;R C(O)OC(O)O&rsqb; R is contacted with a hydroperoxide of formula R &lsqb;OOH&rsqb; in the presence of a base, wherein R represents a mono-, di-, tri- or tetravalent C -C hydrocarbon group, optionally containing one or more hetero atoms, n is 1-4, R represents a C -C hydrocarbon group, optionally containing one or more hetero atoms, R represents a C -C hydrocarbon group, optionally containing one or more hetero atoms, R represents a di-, tri- or tetravalent C -C hydrocarbon group, optionally containing one or more hetero atoms, p is 2-4, R represents hydrogen or a mono- or divalent C -C tertiary alkyl or C -C 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 represents hydrogen, m is 1, provided that if the hydroperoxide is an &agr;,&agr;&prime;-dihydroperoxyperoxide, the reaction is not carried out in an inert two-phase solvent system comprising a polar solvent and an apolar solvent. The invention also relates to a hydroxyperacid, hydroxyperester, and hydroxydiacylperoxide obtainable by said process and the use of said hydroxyperoxides.
