Abstract: The invention relates to ethoxylated phenol- and naphtholcarboxylic acids which are nitrated in the aromatic ring, their preparation and use, in particular in the form of the alkanolamine salts, as low-foam, water-soluble corrosion inhibitors in aqueous systems, and to anti-corrosion agents which contain them.

Abstract: The invention relates to copolymers as ingredients for detergents and cleaning agents, which contain monoethylenically unsaturated mono- and dicarboxylic acids, their hydroxyalkyl esters and, if appropriate, other ethylenically unsaturated compounds as monomer units, and are distinguished by a particular calicum-binding and magnesium-binding capacity, detergents and cleaning agents containing these copolymers, and their use in detergents and cleaning agents, in particular as sequestering agents and anti-redeposition agents.

Abstract: Compounds of the formula where X is a 5-membered heterocyclic structure from the oxazole, oxadiazole, thiazole, thiadiazole, imidazole or triazole series, Y is a radical of the formula +TR the rings A, B and C can be further substituted and can be fused to a benzene ring, R1 and R2 are each hydrogen or unsubstituted or substituted alkyl, aralkyl or cycloalkyl, or R1 and R2 together with the nitrogen are piperidino, pyrrolidino or morpholino, R3 is hydrogen or unsubstituted or substituted alkyl, cycloalkyl, aralkyl, acyl, alkoxycarbonyl, aryloxycarbonyl or arylsulfonyl, and R4 is hydrogen, alkyl or cycloalkyl, are particularly useful as dyes in liquid-crystalline media.
