A number of novel peracid precursors each have the general structure: ##STR1## wherein: Z is a leaving group, the conjugate acid of the leaving group being in the range of from about 4 to 15; R is a substituted or unsubstituted alkyl or alkenyl group having from about 1 to 18 carbon atoms; and M is hydrogen or an alkali or alkaline earth metal. A method is also disclosed for synthesizing a product as represented above wherein succinic anhydride, including an R constituent as defined above is dissolved in a water-miscible, non-nucleophilic solvent and an acid including a Z constituent as defined above is neutralized and deprotonated to form a nucleophile, the substituted anhydride and the nucleophile being combined to form the product. The product is a component in a dry bleach product, optionally including other adjuncts.
A dry bleaching composition comprising a bleach effective amount of a peracid precursor compound of the general structure ##STR11## wherein Z is a leaving group, the conjugate acid of which has a pKa in the range of from about 4 to about 15,
The composition of calim 6 wherein R is an alkyl group having from about eight to twelve carbon atoms and wherein Z is a compound having the general structure ##STR14## wherein R' and Y are optionally substituted at any available respective locations in the structure.
A method for removing soils from fabrics comprising the step of contacting said fabrics in an aqueous solution with a bleaching composition comprising:
