    Abstract: PROBLEM TO BE SOLVED: To produce a new compound useful as a bleach activator for a detergent composition. SOLUTION: This new compound is represented by formula I R1 to R3 are each a 1-24C alkyl or an aryl; R2 and R3 together with N to which both are bonded form a 4-6C ring, etc.; L is a group represented by formula II [(n) is 3-5], etc.; X is an anion}, e.g. (N,N,N-trimethylammonium)acetylpyrrolidone chloride. The compound represented by formula I is obtained by reacting a lactam with chloroacetyl chloride in the presence of an auxiliary base, providing an N-(chloroacetyl)amide, then reacting the resultant compound with a secondary amine, preparing a 2-(N,N-dialkylamine)acetyllactam and subsequently alkylating the resultant compound.

    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: Ammonium nitrile compounds of formula ÄR1N X (I) are new. NR1R2 = 4-6C ring optionally substituted by 1-5C alkyl, 1-5C alkoxy, 1-5C alkanoyl, phenyl, amino, ammonium, CN, cyanamino or Cl, and which may have 1-2 C atoms replaced by O or further N or one C atom replaced by NR6 or R3-N-R6; R3 = 1-24 (preferably1-4)C alkyl, 2-24 (preferably 2-4)C alkenyl, cyanomethyl or 1-4C alkoxy-(1-4C)-alkyl; R4, R5 = H, 1-4C alkyl, 1-4C alkenyl (sic), 1-4C alkoxy-(1-4C)-alkyl, phenyl or 1-3C alkyl-phenyl, preferably H, methyl or phenyl, and most preferably R4 is H when R5 is not H; R6 = H, 1-5C alkyl, 1-5C alkanoyl, 2-5C alkenyl, 2-5C alkynyl, phenyl, 7-9C arylalkyl, 5-7C cycloalkyl, cyanomethyl or CN ; and X = anion. Also claimed are washing and cleaning agents containing a peroxy compound and (I).
