Abstract: A polyester is useful as a high viscosity base fluid. A method for its preparation involves isomerizing an alpha-olefin, epoxidizing an internal olefin, reacting an internal epoxide, and isolating the polyester. Lubricant compositions can contain such polyesters and the compositions are useful as automatic transmission fluids, manual transmission fluids, continuously variable transmission fluids, gear oil formulations, industrial gear oil formulations, axle fluid formulations, dual clutch transmission fluids, dedicated hybrid transmission fluids, or as hydraulic oils.

Abstract: The invention relates to the electrodialytic production of ammonia and sulfuric acid from ammonium-sulfate-rich (waste) waters. An object of said invention was to provide a process for recovering ammonia and sulfuric acid from waters containing ammonium sulfate in high concentrations. The process should be practicable on an industrial scale and have good energy efficiency. This problem is solved by a combination of electrodialysis and water electrolysis. It results in ammonium sulfate being split back into ammonia and sulfuric acid. Unlike conventional three-chamber processes, the process of the invention employs a cell having only two compartments, which can however be multiply parallelized within the stack. This type of scale-up is much more cost-effective than connecting multiple cells in parallel.
Abstract: Compositions that have glycerol fatty acid esters and particular fatty acid amidoalkyl betaines and/or particular alkyl betaines can be used for the thickening of cosmetic formulations. The composition can also be used for thickening an aqueous formulation. The composition also has 3.0% by weight to 20% by weight of glycerol fatty acid esters, wherein the weight percentages are based on the overall composition.

Abstract: A process for catalytic hydrogenation of aromatic amines can be performed. The aromatic amines can be methylenedianiline and/or tolylenediamine. The ring-hydrogenated equivalents can be obtained by contacting an input product, which have the aromatic amines and impurities, such as, alcohols, glycols, polyols, organic acids and/or water, with hydrogen in the presence of a catalyst. The catalyst can be platinum, palladium, rhodium, ruthenium, nickel, cobalt and/or iron. The catalyst is applied to a support, wherein the input product that has aromatic amines result from a PU decomposition process and contains impurities from this decomposition process.
