摘要

There are disclosed salts of amino-(poly)percarboxylic acids having the formula: <CHEM> wherein R, R1 and R2 represent hydrogen or alkyl or two groups R, R1 and R2 are taken together with the nitrogen atom to result in a heterocyclic ring. A represents (cyclo)alkylene , arylene, cycloalkylene-alkylene, alkylene-cycloalkylene, arylene-alkylene or alkylene-arylene, said alkylene units optionally having interspersed CONR3 groups, wherein R3 is hydrogen, alkyl or aryl; X represents HSO4 or CH3SO3; and n is an integer of from 1 to 6. Also disclosed is a process for their preparation and their use as bleaching agents.
