Abstract: The invention set out to improve the oxidizing and bleaching effect of inorganic peroxygen compounds in dishwashing, more particularly machine dishwashing, in terms of their storage stability. This was essentially achieved by using particulate compounds corresponding to formula R1R2R3N+CH2CN X−, in which R1, R2, and R3 independently of one another represent an alkyl, alkenyl or aryl group containing 1 to 18 carbon atoms, in addition to which the groups R2 and R3 may even be part of a heterocycle including the N atom and optionally other hetero atoms, and X is a charge-equalizing anion. Dishwashing detergents, more particularly machine dishwashing detergents, contain about 1% by weight to 10% by weight of this bleach-boosting agent.

Abstract: The invention relates to a method for producing hydrolysis-stable ammonium nitriles by reacting a compound of formula (1), wherein R1, R2, and R3 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 R1 and 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-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—R6 or 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, R4 and R5 are hydrogen, C1-C4-alkyl, C1-C4-alkenyl.

Abstract: Aqueous, alcoholic or aqueous-alcoholic solutions of a monoalkylamine and a reducing sugar are simultaneously injected into a mixing unit and the two solutions are mixed under turbulence in the mixing unit for 6 seconds to 5 minutes at a temperature of 25 to 60° C. and a pressure of 50 to 90 bar. The mixture is then added to a hydrogenation reactor and hydrogenated with hydrogen in the presence of a hydrogenation catalyst. An alkylpolyhydroxyalkylamine is obtained in high yield and with high purity.
