Title:
METHOD FOR PRODUCING HYDROLYSIS-STABLE AMMONIUM NITRILES
Document Type and Number:
WIPO Patent Application WO2002012175
Kind Code:
A3
Abstract:
The invention relates to a method for producing hydrolysis-stable ammonium nitriles by reacting a compound of formula (1), wherein R<1>, R<2>, and R<3> are 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 R<1> and R<2>, 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-C5 alkyl, C1-C5 alkoxy, C1-C5 alkanoyl, 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-R<6> or a group R<3>-N-R<6>, 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, R<4> and R<5> are hydrogen, C1-C4-alkyl, C1-C4-alkenyl, C1-C4-alkoxy-C1-C4-alkyl, phenyl or C1-C3-alkylphenyl, preferably hydrogen, methyl or phenyl, R<4> especially meaning hydrogen when R<5> does 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.
