Polyglycolate compounds are provided having the general structure: ##STR1## wherein n is an integer from 2 to about 10; R is C.sub.1-20 linear or branched alkyl, alkoxylated alkyl, cycloalkyl, aryl, alkylaryl, substituted aryl; R' and R" are independently H, C.sub.1-20 alkyl, aryl, C.sub.1-20 alkylaryl, substituted aryl, and NR.sub.3.sup..alpha.+, wherein R.sup..alpha. is C.sub.1-30 alkyl; and L is a leaving group displaceable in a peroxygen bleaching solution by perhydroxide anion. When this compound is combined with a source of peroxygen in aqueous solution, then a plurality of stain removing peracids are formed. Such peracids are formed substantially sequentially beginning with the carbonyl adjacent to the leaving group L. Thus, a first stain removing peracid having the structure ##STR2## will be formed in amounts approaching quantitative yield.
提供具有一般结构的聚乙二醇化合物:##STR1##
其中n是2到约10的整数;R是C.sub.1-20线性或支链烷基,烷氧基化烷基,环烷基,芳香族,烷基芳香族,取代芳香族;R'和R"独立地是H,C.sub.1-20烷基,芳香族,C.sub.1-20烷基芳香族,取代芳香族和NR.sub.3.sup..alpha. +,其中R.sup..alpha.是C.sub.1-30烷基;L是可以被过氧化氢负离子在过氧化物漂白溶液中取代的离开基。当该化合物与水溶液中的过氧化物源结合时,将形成多种去污过氧酸。这些过氧酸从与离开基L相邻的羰基开始依次形成。因此,将形成具有结构的第一个去污过氧酸##STR2##,其量接近定量收率。
