US 4,902,803 A · Aromatic heterocyclic peroxycarboxylic acids

Abstract

Nitrogen-containing aromatic heterocyclic (poly)peroxycarbonxylic acids having the formula: ##STR1## wherein R represents a hydrogen atom or a straight or branched alkyl, (hetero)cycloalkyl, (hetero)aryl, alkylaryl or arylalkyl group, wherein said groups are optionally substituted, or a carboxylic group or any other substituents non-reactive in the presence of the active oxygen of the peroxycarboxylic group; n is a number selected from 0 and 1; m is a number selected from 1, 2 and 3, and X represents an acidic anion selected from HSO.sub.4.sup.- and CH.sub.3 SO.sub.3.sup.-, and wherein the pyridinic ring may in its turn be condensed with at least one further (hetero) aromatic or (hetero)cycloalkylic ring; to their preparation process and to their use as bleaching agents.
