Definitions
- This invention relates to odorless short chain ammonium nitriles, their granules, and their use for enhancing the bleaching effect of peroxygen compounds in bleaching colored stains on textiles as well as on hard surfaces, as well as detergents and cleaners containing these nitriles as bleach activators.
- Inorganic peroxygen compounds particularly hydrogen peroxide and solid peroxygen compounds which dissolve in water to release hydrogen peroxide, such as sodium perborate and sodium carbonate perhydrate, have long been used as oxidizing agents for disinfecting and bleaching purposes.
- the oxidation effect of these substances in dilute solutions depends strongly on the temperature; Thus, for example, with hydrogen peroxide or perborate in alkaline bleaching liquors only at temperatures above about 80 0 C, a sufficiently fast bleaching of soiled textiles.
- bleach activators are known that the oxidation effect of peroxidic bleaches, such as perborates, percarbonates, persilicates and perphosphates.
- bleach activators Many substances are known in the art as bleach activators. These are usually reactive organic compounds having an O-acyl or N-acyl group which in alkaline solution together with a source of hydrogen peroxide form the corresponding peroxyacids.
- bleach activators include N, N, N ⁇ N'-tetraacetylethylenediamine (TAED), glucose pentaacetate (GPA), xylose tetraacetate (TAX), sodium 4-benzoyloxybenzenesulfonate (SBOBS), sodium trimethylhexanoyloxybenzenesulfonate (STHOBS), tetraacetylglycoluril (TAGU).
- 1-phenyl-3-acetylhydantoin PAH
- NOBS sodium nonanoyloxy-benzenesulfonate
- ISONOBS isononanoyloxy-benzenesulfonate
- An interesting group is cationic compounds containing a quaternary ammonium group, since they are highly effective bleach activators.
- a major drawback of said bleach activators is that they mostly leave large volume leaving groups (e.g., phenolsulfonates) after perhydrolysis, which are of no importance to the bleaching process.
- bleach activators are of interest in which a highly reactive peracid but no leaving group is released in the perhydrolysis step. This is e.g. achieved by a cyano group. In perhydrolysis, this probably forms a peroxyimidic acid, which then acts as a bleaching agent.
- Examples include ammonium nitriles, characterized by the structural element
- X is an anion, for example chloride, sulfate, hydrogensulfate, methylsulfonate, ethanesulfonate, toluenesulfonate, benzenesulfonate or cumene sulfonate
- anion for example chloride, sulfate, hydrogensulfate, methylsulfonate, ethanesulfonate, toluenesulfonate, benzenesulfonate or cumene sulfonate
- the higher homologue (dimethylethylammonium acetonitrile tosylate) also releases traces of trimethylamine under alkaline conditions.
- traces of trimethylamine can be detected even from N-methylmorpholinium acetonitrile methosulfate.
- the mechanism of formation is unclear, but it is likely that one of the nitrogen groups bound to ammonia transferred, which is released by hydrolysis of the nitrile. Repeated methyl group transfer then forms traces of trimethylamine.
- N-methyl-ammonium nitriles of the type described above which have two ethyl substituents, are effective bleach activators which do not form trimethylamine under alkaline conditions, even though one methyl group is still on the nitrogen.
- the present invention thus relates to compounds of the general formula
- X is an anion, for example chloride, bromide, sulfate, hydrogensulfate, methosulfonate, ethanesulfonate, toluenesulfonate, benzenesulfonate or cumene sulfonate, particularly preferably the anions chloride, hydrogensulfate, sulfate, methosulfate and toluenesulfonate.

- the salt can be recovered by conventional methods of workup such as extraction, crystallization, suction filtration, washing of the crystal slurry on the filter and drying.
- Analog can be assumed to be ethylmethylamine, wherein the quaternization is then carried out with an ethyl derivative.
- the resulting dialkylaminoacetonitrile is taken up in an organic solvent and reacted with an alkylating agent such as methyl chloride, dimethyl sulfate or Arylsulfonklarealkylester at temperatures between 20 and 100 0 C to the corresponding N-cyanomethyl-ammonium salt.
