Abstract
The invention relates to a method for producing hydrolysis-stable ammonium nitriles by reacting a compound of formula (1), wherein R, R, and Rare identical or different and represent linear or branched C–C-alkyl groups, C–C-alkenyl groups, substituted or non-substituted benzyl or C–C-alkoxy-C–C-alkyl groups, or wherein Rand R, together with the nitrogen atom to which they are bonded, form a ring with 4 to 6 C-atoms which can be substituted with C–Calkyl, C–Calkoxy, C–Calkanoyl, phenyl, amino, ammonium, cyano, cyanamino, chlorine or bromine and which can contain in addition to the nitrogen atom, instead of the carbon atoms, one or two oxygen or nitrogen atoms, a group N—Ror a group R—N—R, wherein R6 is hydrogen, C–C-alkyl, C–C-alkenyl, C–C-alkinyl, phenyl, C–C-aralkyl, C–C-cycloalkyl, C–C-alkanoyl, cyanomethyl or cyan, Rand Rare hydrogen, C–C-alkyl, C–C-alkenyl, C–C-alkoxy-C–C-alkyl, phenyl or C–C-alkylphenyl, preferably hydrogen, methyl or phenyl, Respecially meaning hydrogen when Rdoes not mean hydrogen, and X represents an anion; with an alkaline or ammonium salt of an alkane sulfonate, paraffin sulfonate, aryl sulfonate, alcohol sulfate or fatty acid alkyl carboxylate in the presence of water, at a high temperature
