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.
本发明涉及一种制备过酸、过酯或双酰过氧化物的方法,其特征在于将式R1[C(O)OC(O)OR2]n或[R3C(O)OC(O)O]pR4的混合酸酐与式R5[OOH]的过氧化氢在碱的存在下接触,其中R1表示一个单、双、三或四价的C1-C19烃基,可选地含有一个或多个杂原子,n为1-4,R2表示一个C1-C20烃基,可选地含有一个或多个杂原子,R3表示一个C1-C19烃基,可选地含有一个或多个杂原子,R4表示一个双、三或四价的C1-C20烃基,可选地含有一个或多个杂原子,p为2-4,R5表示氢或一个单价或双价的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表示氢,则m为1,但如果过氧化氢是α,α'-二过氧基过氧化物,则不在惰性双相溶剂系统中进行反应,该系统包括一个极性溶剂和一个非极性溶剂。本发明还涉及通过该方法获得的羟基过酸、羟基过酯和羟基双酰过氧化物以及所述羟基过氧化物的用途。
