摘要:
The invention comprises heterocyclic cationic activators with the structure of Formula (I) that are capable of forming a peroxyimidic acid with a source of active oxygen in aqueous solution or being in a peroxyimidic form wherein A, R1, R2, R3, Y, and Z are as defined in the disclosure. The activators of Formula (I) are admixed with another compound selected from anionic species either capable of forming a peracid with a source of active oxygen in aqueous solution, or being in a peracid form, or a non-ionic polarizable activator and suitable counterion.
摘要:
Nitrile activators, such as N-alkyl ammonium acetonitrile activators, are combined with a source of active oxygen as cleaning and bleaching compositions. Preferred activator embodiments of the invention include salts of N-methyl morpholinium acetonitrile, N-butylmorpholinium acetonitrile, N-hexyl morpholinium acetonitrile, and N-octyl morpholinium acetonitrile. A particularly preferred activator embodiment is an N-methyl morpholinium acetonitrile salt. The nitrile and active oxygen react to form a bleaching agent which is applied to a stain on an article. The treated stain is coctacted with dense gas so as to provide substantially non-aqueous stain removal. One embodiment is a composition in which the nitrile and active oxygen are disposed in the dense carbon dioxide.
