Abstract: The invention relates to branched polyesters with sulfonate groups. The polyesters can be obtained by reacting the components A, B, optionally C, and optionally D into branched polyesters, wherein the component A is selected from the group consisting of a,ß-olefinically unsaturated dicarboxylic acids, the component B is selected from the group consisting of di- or higher-functional alcohols, the optional component C is selected from the group consisting of di- or higher-functional carboxylic acids and hydroxy carboxylic acids without a,ß-olefinically unsaturated bonds, and the optional component D is selected from the compounds of formula CH3(-O-CH2-CH2)n-OH, with the proviso that if only di-functional alcohols are selected as component B, the component C is present during the reaction and is selected from the group of the tri- or higher-functional carboxylic acids and the tri- or higher-functional hydroxy carboxylic acids without a,ß-olefinically unsaturated bonds. The obtained branched polyesters are subsequently reacted with hydrogen sulfite, the molar quantity of hydrogen sulfite being at most 95 mol% with respect to the quantity of a,ß-olefinically unsaturated dicarboxylic acids.

Abstract: Disclosed is a process for the acid digestion of metal-comprising compounds by leaching by means of an aqueous leachant, wherein the leachant comprises i) one or more alkanesulfonic acids with a propyl, ethyl or methyl moiety and sulphuric acid at a weight ratio of alkanesulfonic acid to sulfuric acid from 1 : 1000 to 1 : 1, and/or ii) a mixture of one or more salts of alkanesulfonic acids with a propyl, ethyl or methyl moiety and sulfuric acid at a weight ratio of salt of alkanesulfonic acid to sulfuric acid is from 1 : 9 to 1 :99. Also disclosed is said leachant used in the process.
