Abstract

The invention relates to ammonium nitriles of general formula (I), wherein the radicals R 3 , R 4 , R 5 and X − have the meaning as cited in the description and R 1 and R 2 respectively represent individually a straight or branched chained C 5 –C 24 -alkyl, alkenyl or alkylether group. The inventive compounds are used as bleaching activators in washing, cleaning, and disinfective agents and in textile and paper bleaching.

Claims (12)

1. A washing, cleaning or disinfecting composition comprising a surfactant and a compound of the formula (I)

in which R 1 and R 2 are in each case individually a straight-chain or branched-chain,

R 3 is methyl,

R 4 and R 5 are hydrogen, C 1 –C 4 -alkyl, C 2 –C 4 -alkenyl, C 1 –C 4 -alkoxy-C 1 –C 4 -alkyl, phenyl, C 1 - to C 3 -alkylphenyl or together with the common carbon atom form a C 5 –C 7 -cycloalkyl group, R 4 is hydrogen if R 5 is not hydrogen, and

X − is an anion.

2. A composition as claimed in claim 1 , wherein R 1 and R 2 are in each case individually a C 5 –C 18 -alkyl, alkenyl or alkyl ether group.

3. A composition as claimed in claim 1 , wherein R 4 and R 5 are hydrogen.

4. A composition as claimed in claim 1 , wherein X − is chloride, bromide, iodide, fluoride, sulfate, hydrogensulfate, carbonate, hydrogencarbonate, phosphate, mono- and dihydrogenphosphate, pyrophosphate, metaphosphate, nitrate, methosulfate, dodecylsulfate, dodecylbenzenesulfonate, phosphonate, methylphosphonate, methanedisulfonate, methylsulfonate, ethanesulfonate, toluenesulfonate, benzenesulfonate or cumenesulfonate.

5. A composition as claimed in claim 1 , wherein R 1 and R 2 is C 6 –C 10 -alkyl, R 3 is methyl, R 4 and R 5 are hydrogen and X − is an anion.

6. A composition as claimed in claim 1 , wherein R 1 and R 2 is C 6 –C 10 -alkyl, R 3 is methyl, R 4 and R 5 are hydrogen and X − is chloride, hydrogensulfate, sulfate, methosulfate, toluenesulfonate, benzenesulfonate or cumenesulfonate.

7. A bleaching composition for the bleaching of textile material and paper comprising a peroxygen bleachand a compound of the formula (I)

in which R 1 and R 2 are in each case individually a straight-chain or branched-chain C 5 –C 24 alkyl, R 3 is methyl, R 4 and R 5 are hydrogen, C 1 –C 4 -alkyl, C 2 –C 4 -alkenyl, C 1 –C 4 -alkoxy-C 1 –C 4 -alkyl, C 1 - to C 3 -alkylphenyl or together with the common carbon atom form a C 5 –C 7 -cycloalkyl group, R 4 is hydrogen if R 5 is not hydrogen, and X − is an anion.
