Abstract: The invention relates to a process for the preparation of organic disulfides by oxidation of mercaptans with sulfur dissolved in an organic disulfide using an amine as catalyst, where the mercaptans are used as "crude mercaptan stream" from a reaction of alcohols with hydrogen sulfide over a catalyst suitable for mercaptan synthesis. Furthermore, the invention relates to the use of the organic disulfides for the preparation of alkanesulfonic acids.

Abstract: The invention relates to a process for the electrolytic coating of metals with zinc or a zinc alloy in which matt surfaces are obtained, by deposition of zinc from an electrolyte solution comprising a zinc salt selected from zinc sulfate or an alkanesulfonate of zinc or mixtures thereof, and, if desired, further metal salts, an acid selected from sulfuric acid or an alkanesulfonic acid or a mixture of the two acids, and at least one additive for improving the surface roughness and preventing dendritic edge growth, selected from nitrogen-containing surface-active compounds, which may be ionic or nonionic, sulfur-containing anionic surface-active compounds, and surface-active compounds based on multifunctional alcohols having at least three hydroxyl groups. The invention furthermore relates to an electrolyte composition for electrolytic coating of metals with zinc or zinc alloys, and to the use of said additives for improving the surface roughness and preventing dendritic edge growth in the electrolytic coating of metals with zinc or a zinc alloy in an alkanesulfonic acid-containing electrolyte.

Abstract: A composition for the surface treatment of metals and for the deposition of metals or metal alloys and plastics surfaces comprises a) at least one polymer as component A, comprising at least one structural unit of the formula (I) where this structural unit may be part of a polymer main chain or may be bound to a polymer main chain via an anchor group, and M is hydrogen or an ammonium or metal cation; b) water or another solvent which is suitable for dissolving, dispersing, suspending or emulsifying the polymer (component A), as component B; c) if required, surface-active compounds, dispersants, suspending media and/or emulsifiers as component C; either d) if required, a salt, an acid or a base based on transition metal cations, transition metal oxoanions, fluorometallates or lanthanoids as component D, and/or e) at least one acid selected from the group consisting of phosphoric acid, sulfuric acid, sulfonic acid, nitric acid, hydrofluoric acid and hydrochloric acid as component E, or a base and/or f) at least one metal oxide and/or metal salt as component F. Furthermore, in a process for the surface treatment of metals and in a process for the deposition of metals or metal alloys on a metal surface or plastics surface, the metal surface or plastics surface is brought into contact with a polymer (component A). Moreover, polymers (component A) are used for the surface treatment of metals and for the deposition of metals or metal alloys on a metal surface or plastics surface.
