The bleaches are of the quaternary oxaziridinium salt type. Substrates such as fabrics may be bleached in an aqueous solution containing the quaternary oxaziridinium salt.

Abstract: A process is reported for the preparation of bis(amidocarboxylic acid) involving the steps of:(i) charging a reactor with an acyl halide and an aminocarboxylate compound being formed from and selected from lactams and aminocarboxylic acids;(ii) slowly adding to the reaction medium an alkali at a rate to maintain a pH between 10 and 14; and(iii) recovering the bis(amidocarboxylic acid) from the reaction medium.The recovery procedure advantageously includes acidification of the reaction medium to a pH between 4.5 and 7. The preferred product of the process is N,N'-terephthaloyl-di(6-aminocaproic acid).
