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]pR4 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 C1-C19 hydrocarbon group, optionally containing one or more hetero atoms, n is 1-4, R2 represents a C1-C20 hydrocarbon group, optionally containing one or more hetero atoms, R3 represents a C1-C19 hydrocarbon group, optionally containing one or more hetero atoms, R4 represents a di-, tri- or tetravalent C1-C20 hydrocarbon group, optionally containing one or more hetero atoms, p is 2-4, R5 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 R5 represents hydrogen, m is 1, provided that if the hydroperoxide is an &agr;,&agr;′-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.
该发明涉及一种制备过氧酸、过氧酯或二酰过氧化物的方法,其特征在于将式R1[C(O)OC(O)OR2]n或[R3C(O)OC(O)O]pR4的混合酐与式R5[OOH]m的过氧化氢在碱存在下接触,其中R1代表一个单价、二价、三价或四价的C1-C19烃基,可选地含有一个或多个杂原子,n为1-4,R2代表一个C1-C20烃基,可选地含有一个或多个杂原子,R3代表一个C1-C19烃基,可选地含有一个或多个杂原子,R4代表一个二价、三价或四价的C1-C20烃基,可选地含有一个或多个杂原子,p为2-4,R5代表氢或一个单价或二价的C3-C18三级烷基或C2-C20酰基,其中该三级烷基或酰基可选地含有一个或多个杂原子,m为1或2,如果R5代表氢,则m为1,前提是如果过氧化氢是α,α′-二过氧基过氧化物,则反应不在惰性两相溶剂体系中进行,该体系包括极性溶剂和非极性溶剂。该发明还涉及通过所述方法获得的羟基过氧酸、羟基过氧酯和羟基二酰过氧化物,以及所述羟基过氧化物的用途。
