ABSTRACT:
The invention relates to a method for producing hydrolysis-stable ammonium nitriles by reacting a compound of formula (1), wherein R1, R2, and R3are identical or different and represent linear or branched C1–C24-alkyl groups, C2–C24-alkenyl groups, substituted or non-substituted benzyl or C1–C4-alkoxy-C1–C4-alkyl groups, or wherein R1and R2, together with the nitrogen atom to which they are bonded, form a ring with 4 to 6 C-atoms which can be substituted with C1–C5alkyl, C1–C5alkoxy, C1–C5alkanoyl, 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—R6or a group R3—N—R6, wherein R6 is hydrogen, C1–C5-alkyl, C2–C5-alkenyl, C2–C5-alkinyl, phenyl, C7–C9-aralkyl, C5–C7-cycloalkyl, C1–C6-alkanoyl, cyanomethyl or cyan, R4and R5are hydrogen, C1–C4-alkyl, C1–C4-alkenyl, C1–C4-alkoxy-C1–C4-alkyl, phenyl or C1–C3-alkylphenyl, preferably hydrogen, methyl or phenyl, R4especially meaning hydrogen when R5does 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
