Die Erfindung betrifft ein Verfahren zur Reinigung eines Abwassers enthaltend mindestens eine kurzkettige Etherverbindung, umfassend die Schritte:a) Inkontaktbringen des Abwassers mit einem Adsorbens, das einen hydrophoben Zeolithen enthält, in einer Säule, um die Adsorption der kurzkettigen Etherverbindung durch das Adsorbens zu bewirken,b) Trennen des Abwassers von dem Adsorbens, undc) Desorption der kurzkettigen Etherverbindung von dem Adsorbens, unter Bedingungen, die eine Desorption bewirken, dadurch gekennzeichnet, dass das Adsorbens während der Schritte a) bis c) in der Säule bleibt.

The present invention relates to a methanol catalyst with improved activity and stability, its preparation and a process for methanol synthesis by use of such catalyst.

The present application describes coolants with low electrical conductivity, the corresponding coolant concentrates, and the use of such coolants in cooling systems of vehicles with electric engines, fuel cells or hybrid engines with a combination of combustion engines with electric engines or a combination of combustion engines with fuel cells, comprising (A) at least one alkylene glycol (B) water (C) at least one azole derivative (D) at least one tertiary amine (E) at least one mono- or di-carboxylic acid (F) a phosphonic acid derivative (G) optionally at least one further coolant additive.

The present invention relates to the use of amphiphilic compounds as antimicrobial agents specifically effective against obligate anaerobic bacteria under strict anaerobic conditions. The compounds include glyceryl ethers, glyceryl esters, sorbitan esters, isosorbide esters, and N-methyl cyclic glucamides of formula (I):wherein R is a saturated or unsaturated hydrocarbon chain having 5 to 23 carbon atoms. The compounds demonstrate antimicrobial activity against clinically relevant obligate anaerobic bacteria when tested under strict anaerobic conditions that accurately reflect the natural environments where these bacteria thrive. The invention provides compounds for therapeutic and non-therapeutic uses targeting obligate anaerobic bacteria, as well as antimicrobial compositions suitable for personal care, cosmetic, and pharmaceutical applications.

The present invention relates to a method for filling a reactor with a tubular loading device having a structured inner surface.
