    Abstract: PROBLEM TO BE SOLVED: To provide a bleaching activator which has improved solubility and compatibility with fibers and exhibits a better bleaching action than that of a conventional bleaching activator by selecting a specific compd. as or incorporating it into a bleaching activator. SOLUTION: This bleaching activator is or contains a compd. represented by the formula (wherein R1 is H, a 1-24C alkyl, a 2-24C alkenyl, an aryl, cyanomethyl, or a 1-4C alkoxy-(1-4C) alkyl; R2 to R4 are each H, a 1-24C alkyl, a 2-24C alkenyl, an aryl, a 1-4C alkoxy-(1-24C) alkyl, or cyano; when Z is cyano, then Y is the same as R2 to R4 , and when Y is cyano, then Z is the same as R2 to R4 ; and X is an anion). The synthetic route is as follows: for example, isonicotinonitrile is obtd, by a known method, i.e., by the direct oxidation or ammonoxidation of 4-methylpyridine; and, for example, a corresponding N- alkyl-4-cyanopyridinium salt is obtd. by the alkylation of isonicotinonitrile with a methylation agent (e.g. methyl chloride or dimethyl sulfate).

    Abstract: The invention relates to dispersing agents based on a mixture of at least one compound of the formula 1 in which Ar is benzene or naphthalene, X is -CH2-CH2- and/or -CH2-CH(CH3)-, 0 to (m-1) of the radicals A are hydrogen, 1 to m of the radicals A are benzoyl and/or naphthoyl, 1 to m of the radicals A are -CO-CM=CH-COOM and/or -CO-CH2-CH(SO3M)-COOM, M being a cation, R , R and R are hydrogen and/or alkyl having 1 to 14 carbon atoms, R is hydrogen and/or alkyl having 1 to 9 carbon atoms, n is a number from 1 to 150 and m is a number from 2 to 12, with compounds of the formula 2 in which R and R independently of one another are an alkyl group from methyl to butyl and are in the m-position relative to the hydroxyl group, R is hydrogen or methyl and Me is a cation, especially a proton or an alkali metal cation, alkaline earth metal cation or ammonium cation, and x and y are the numbers 0, 1 and 2, the total of these numbers being at least 1. The dispersing agents according to the invention are suitable for preparing dispersions of dyes, pigments, plant protection agents and pesticides and for preparing dyeing baths, padding baths and pastes for paper printing and textile printing.
