摘要： The ampholytes are extracted from the reaction solution with a liquid cation exchanger which is immiscible with the acidic aqueous reaction solution, where the cation exchanger is dissolved in at least one organic solvent which is immiscible with water and forms an organic phase with the organic solvent. Subsequently the organic phase which is loaded with the ampholyte is separated from the reaction solution, and then the ampholytes are back-extracted from the organic phase with aqueous solvents. The product losses in the process are low, and the residual salt content is very low.

摘要： A process for scavenging hydrogen sulfide from gases, in which the hydrogen sulfide-containing gas is introduced into an aqueous glyoxal solution of at least 15% by weight strength at a pH of a solution of 5 to 11 until the molar ratio of glyoxal to hydrogen sulfide is 3 to 2. The solid reaction product obtained in this way, which contains the hydrogen sulfide in bound form, is separated off. Owing to its stability and insolubility in acids and bases, it can be disposed of without problems.
