The present invention relates to a process for producing lubricating grease by adding a polymeric structure improver in a composition liquid at 25&#xb0; C. to the dispersion to a dispersion which has grease structure and comprises at least one thickener and at least one lubricating oil.

Process for producing lubricating grease

The present invention relates to processes for preparing carboxylic acid derivatives, comprising the reaction of at least one carboxylic acid and/or of a carboxylic acid derivative with at least one alcohol and/or an amine in the presence of a metal-containing catalyst, wherein, after the reaction has ended, the metal-containing catalyst is contacted with water and a superabsorbent, the contacting of the catalyst with the water leading to hydrolysis of the catalyst. The present invention further relates to the use of superabsorbents for removing a metal-containing catalyst from a mixture after hydrolysis of the catalyst.

Process for preparing carboxylic acid derivatives

The present invention is directed to a lubricating oil composition, a diesel engine comprising a lubricating oil composition, and a method of lubricating a diesel engine provided with an exhaust gas recirculation system, comprising lubricating said engine with a lubricating oil composition comprising an oil of lubricating viscosity, and a polymeric N-dispersant booster comprising monomer units of:   

Oil composition for lubricating an EGR equipped diesel engine and an EGR equipped diesel engine comprising same

The present invention is directed to a lubricating oil composition, a diesel engine comprising a lubricating oil composition, and a method of lubricating a diesel engine provided with an exhaust gas recirculation system, comprising lubricating said engine with a lubricating oil composition comprising an oil of lubricating viscosity, and a polymeric N-dispersant booster.

The present invention relates to lubricating greases comprising at least one thickening agent and at least one lubricating oil, wherein the lubricating grease contains at least one polymeric structure improver that can be obtained by polymerization of monomer compositions, which are composed of in which R represents hydrogen or methyl, Rdenotes a straight-chain or branched alkyl moiety having 1 to 5 carbon atoms, in which R represents hydrogen or methyl, Rdenotes a straight-chain or branched alkyl moiety having 6 to 30 carbon atoms,
