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 hard material sintered compacts with a nickel- and cobalt-free, nitrogenous steel as binder of the hard phase. The invention further relates to a method for producing said hard material sintered compacts by methods of powder metallurgy, especially by powder injection molding, and to powder injection molding masses for producing said hard material sintered compacts by powder injection molding.

Abstract: The invention relates to a method of producing organic disulfides by oxidizing mercaptans with sulfur which is dissolved in an organic disulfide and using an amine as the catalyst. Said mercaptans are used as "crude mercaptan flow" from a reaction of alcohols with hydrosulfide on a catalyst suitable for the synthesis of mercaptan. The invention also relates to the use of said organic disulfides for producing alkane sulfonic acids.

Abstract: The invention relates to the application of at least one ester of general formula (I) to (V), whereby R , R , R , R are the same or different and each, independent of one another, represent a linear or branched-chain C1 to C4 alkyl group, (-CH2-CH2-O)n-CH3 with n=1 to 3, a C3 to C6 cycloalkyl group, and an aromatic hydrocarbon group which can be substituted. At least one of the groups R , R , R or R represents (-CH2-CH2-O)n-CH3 with n=1 to 3. The inventive ester can be used as a solvent in electrolyte systems for Li ion accumulators.
