摘要:
A process of removing soil and/or stains from fabrics by immersing the fabrics in a peroxygen bleach bath containing as a peroxygen activator a disulfone of the formulaRSO.sub.2 SO.sub.2 R.sub.1wherein R and R.sub.1, which may be alike or different, are each selected from the class consisting of an alkyl radical of 1 to 18 carbon atoms; a cycloalkyl radical of 3 to 7 carbon atoms said alkyl and cycloalkyl radicals bearing optional substituents selected from the group consisting of lower alkoxyl, fluoro and chloro; and an aromatic radical selected from the group consisting of phenyl, naphthyl and heterocyclic having 1 ring or 2 fused rings containing 5 to 6 members of which 1 to 2 are heteroatoms selected from the class consisting of nitrogen, oxygen and sulfur, said aromatic radicals optionally bearing 1 to 3 substituents selected from the class consisting of nitro, alkyl of 1 to 16 carbon atoms, alkoxy of 1 to 16 carbon atoms, aliphatic carboxamido of 1 to 16 carbon atoms, benzamido, chlorine and bromine. Aromatic is used herein in its modern sense to signify an organic ring system having aromatic character including both aromatic hydrocarbon and heterocyclic ring systems. Also described are dry blend compositions containing the bleach bath components.
