Abstract: The use of imidazolium salts (I) where R1 and R3 are each independently an organic radical having 1 to 3000 carbon atoms, R2, R4 and R5 are each independently hydrogen or an organic radical having 1 to 3000 carbon atoms, X is an anion and n is the number 1, 2 or 3 as additives for fuels, especially as detergent additives for diesel fuels, as wax antisettling additives for middle distillate fuels and as lubricity improvers, and for improving the use properties of mineral and synthetic nonaqueous industrial fluids.

Abstract: The present invention relates to novel quaternized nitrogen compounds, to the preparation thereof and to the use thereof as a fuel and lubricant additive, more particularly as a detergent additive; to additive packages which comprise these compounds; and to fuels and lubricants thus additized. The present invention further relates to the use of these quaternized nitrogen compounds as a fuel additive for reducing or preventing deposits in the injection systems of direct-injection diesel engines, especially in common-rail injection systems, for reducing the fuel consumption of direct-injection diesel engines, especially of diesel engines with common-rail injection systems, and for minimizing power loss in direct-injection diesel engines, especially in diesel engines with common-rail injection systems.

Abstract: Polytetrahydrobenzoxazines and bistetrahydrobenzoxazines, obtainable by (A) reacting at least one diamine of the formula H2N-A-NH2 with a C1- to C12-aldehyde and a C1- to C8-alkanol at 20 to 80° C. with elimination and removal of water, (B) reacting the condensation product from (A) with a phenol which bears a long-chain substituent at 30 to 120° C., and optionally (C) heating the reaction product from (B) to 125 to 280° C. The resulting polytetrahydrobenzoxazines and bistetrahydrobenzoxazines are suitable as fuel or lubricant additives, especially as detergent additives for diesel fuels.

Abstract: The use of the reaction product formed from a hydrocarbyl-substituted dicarboxylic acid or anhydride thereof and a nitrogen compound I or a salt thereof as an additive in a fuel for reducing fuel consumption in gasoline engines.

Abstract: Disclosed is the use of benzylidene malonates of formula (1) wherein R1 is methyl; ethyl; propyl; or n-butyl; if R1 is methyl, then R is tert. butyl; a radical of formula (1a) or a radical of formula (1b) wherein R2 and R3, independently from each other are hydrogen; or methyl; R4 is methyl; ethyl; or n-propyl; R5 and R6 independently from each other are hydrogen; or C1-C3alkyl; if R1 is ethyl; propyl; or n-butyl, then R is isopropyl; for the protection of human and animal hair and skin against UV radiation.

Abstract: Disclosed is the use of a UV filter combination, comprising (a) a first UV filter selected from benzylidene malonates of formula (1), wherein R1 methyl; ethyl; propyl; or n-butyl; if R1 is methyl, then R is tert.

Abstract: New types of derivatives of tris(2-hydroxyphenyl)methanes which have, as functional groups, polyalkoxy groups or polyalkoxy groups modified with terminal hydrophilic groups, preparation of such compounds and their use, especially as surfactants and thickeners.
