    • 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.
    • 提供了具有以下通用结构的聚乙醇酸酯化合物:其中n为2至约10的整数; R为C 1-20直链或支链烷基,烷氧基化烷基,环烷基,芳基,烷基芳基,取代芳基; R'和R“独立地为H,C 1-20烷基,芳基,C 1-20烷基芳基,取代的芳基和NR 3α+,其中Rα为C 1-30烷基; L是在过氧漂白溶液中通过全氢氧化物阴离子置换的离去基团。 当该化合物与水溶液中的过氧源组合时,形成多个去污过酸。 这样的过酸基本上是从与离去基团L相邻的羰基开始形成的。因此,具有接近定量收率的量的第一种去除污垢的过酸的结构将形成。

    • The invention provides novel peracid precursors representative of which is the structure: ##STR1## wherein R.sup.1 is alkyl of 1 to 20 carbon atoms; R.sup.2 is OH, --O--R.sup.3, or ##STR2## and X.sup.1, X.sup.2, Y and Z are individually selected from H, SO.sub.3.sup.--, CO.sub.2.sup.--, NO.sub.2, NR.sub.4.sup.5+, halogen, R.sup.6 and mixtures thereof;wherein R.sup.3 of --O--R.sup.3 is alkyl of 1 to 20 carbon atoms; R.sup.4 of ##STR3## is alkyl of 1 to 20 carbon atoms; R.sup.5 of NR.sub.4.sup.5+ is selected from H, alkyl of 1 to 24 carbon atoms and mixtures thereof; and R.sup.6 is alkyl of 1 to 20 carbon atoms.In one embodiment of the invention, the novel peracid precursors are combined with a source of hydrogen peroxide and sufficient quantities of buffer to impact an alkaline pH when the composition is placed in aqueous solution. Preferred embodiments of the invention include wherein R.sup.2 is hydroxy, and R.sup.1 is alkyl of 1 to 20 carbon atoms (monoester); and wherein R.sup.2 is ##STR4## and R.sup.1 and R.sup.4 are alkyls of 1 to 20 carbon atoms (diester) and may be either symmetrical (i.e., R.sup.1 =R.sup.4) or mixed (i.e., R.sup.1 .noteq.R.sup.4). The mixed diester embodiment appears to provide benefits of mixed hydrophobic/hydrophilic peracid generation to oxidize both hydrophobic and hydrophilic soils. Various detergent adjuncts known to those skilled in the art may be added, such as surfactants, builders, fragrances, antimicrobial compounds and the like.
