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 method for producing gold-coloured aluminium oxid e layers, whereby the oxidised surface of the aluminium or aluminium alloy is coloured in an electrolyte containing an alkane sulfonic acid and a silver alkane sulfonate by means of an electrolytic method. The invention also relates to using of the gold-coloured aluminium or aluminium alloy workpiece s produced by said method for decorative purposes. The invention further relat es to an electrolyte solution for the gold coloration of the oxidised surface o f aluminium or an aluminium alloy by means of an electrolytic method, and the use of an electrolyte containing a silver alkane sulfonate for the gold coloration of aluminium oxide layers in aluminium and aluminium alloys in an electrolytic method.
