A composition for the treatment of metal surfaces and for the deposition of metals or metal alloys on plastics surfaces contains  b) water or another solvent which is suitable for dissolving, dispersing, suspending or emulsifying the polymer, as component B;c) if required, surface-active compounds, dispersants, suspending media and/or emulsifiers as component C. In a process for the treatment of a metal surface and a process for the deposition of metals or metal alloys on a plastics surface, the metal or plastics surface is brought into contact with a polymer (component A). Furthermore, polymers (component A) are used for the treatment of metal surfaces and for the deposition of metals or metal alloys on a plastics surface, and polymers composed of special components A'a, A&#x2032;b and A&#x2032;c.

Polymer derivatives for the treatment of metals

A process is described for the catalytic removal of HS gas from a sour gas stream in the presence of a chelate ligand of the formula (I) A mixture is also described for removing HS gas from a sour gas stream, the mixture comprising an aminocarboxylate-containing metal chelate complex, and the use is also described of an aminocarboxylate-containing metal chelate complex for removing HS gas from a sour gas stream.

Method for desulphurizing acid gases using catalysts that are insensitive to oxidation and contain aminocarboxylate

The invention describes a process for the preparation of surfactant alcohols and surfactant alcohol ethers which are, inter alia, highly suitable as surfactants or for the preparation of surfactants. The process, starting from olefin mixtures having a defined minimum content of linear hexenes, gives mixtures having a predominant fraction of branched dodecenes, which are subsequently derivatized to give surfactant alcohols and then optionally alkoxylated. The surfactant alcohol mixture obtained in the process has a degree of branching of from 2.0 to 3.0 and in particular exhibits advantageous properties as regards ecotoxicity and biodegradability. A description is also given of the use of the surfactant alcohols and surfactant alcohol ethers as surfactants by glycosidation or polyglycosidation, sulfation or phosphation.
