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<1>[C(O)OC(O)OR<2>]n or [R<3>C(O)OC(O)O]pR<4 >is contacted with a hydroperoxide of formula R<5>[OOH]m in the presence of a base, wherein R<1 >represents a mono-, di-, tri- or tetravalent C1-C19 hydrocarbon group, optionally containing one or more hetero atoms, n is 1-4, R<2 >represents a C1-C20 hydrocarbon group, optionally containing one or more hetero atoms, R<3 >represents a C1-C19 hydrocarbon group, optionally containing one or more hetero atoms, R<4 >represents a di-, tri- or tetravalent C1-C20 hydrocarbon group, optionally containing one or more hetero atoms, p is 2-4, R<5 >represents hydrogen or a mono- or divalent C3-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 alpha,alpha'-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.
