    摘要： 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.

    摘要： A perhydrolysis system is provided which includes peroxyacid precursors and a source of peroxygen. Upon dissolution in water these compositions provide high yields of a novel peroxyacid having the structure ##STR1## where R is hydrogen or an alkyl of not more than 5 carbon atoms. The precursors may include hydroxyl nitrogen derivatives as leaving groups, since the .alpha.-substituted phenoxy moiety enhances carbonyl reactivity toward perhydroxyl anion.

    摘要： Novel sulfonated phenyl esters of dicarboxylic acids are useful as diperoxyacid precursors in bleaching and laundering applications when combined with a source of peroxide. These diperoxyacid precursors can be produced by reacting a dicarboxylic acid, a phenol sulfonate, and a lower alkyl acid anhydride in an alkyl hydrocarbon solvent and removing a carboxylic acid byproduct through distillation. The diperoxyacid precursors have the structure: ##STR1## wherein n is an integer from about 4 to about 18 and M is an alkali metal, an alkaline earth metal, or ammonium. The diperoxyacid precursors have a high perhydrolysis profile coupled with a relatively low-to-moderate hydrolysis profile.
