Abstract:
The invention relates to a method for producing bifunctional ammonium nitriles by reacting a dihalogenalkyl compound or a dihalogenaryl compound with a dialkylaminoacetonitrile in a polar, aprotic solvent. Bifunctional ammonium nitriles may be used as bleach activators in detergents and cleaners.
Abstract:
The invention relates to a method for producing bifunctional ammonium nitriles of the following general formulae: by reacting a tertiary diamine with a cyanomethylene-group-transferring quaternizing agent in a polar, aprotic solvent. Bifunctional ammonium nitriles may be used as bleach activators in detergents and cleaners.
