摘要： The invention relates to a process for reprocessing alkane sulfonic acid, which is used in a chemical process as an agent, catalyst, or solvent, which comprises the following steps: (a) separating a stream containing alkane sulfonic acid from a reaction mixture which accumulates in the chemical process, (b) feeding the stream containing alkane sulfonic acid as output melt to melt crystallisation, wherein crystals of the alkane sulfonic acid, of hydrates of the alkane sulfonic acid or a mixture of the two are formed, suspended in mother liquor, (c), carrying out a solid-liquid separation in order to separate crystals out of the mother liquor, (d) if necessary, washing the crystals in order to remove mother liquor adhering to the crystals, (e) feeding back the crystals separated from the mother liquor and possibly washed into the chemical process.

摘要： The invention relates to a method for reducing or preventing the decomposition of a composition Z, containing Z1 a salt of dithionous acid in an amount in the range of 50 to 100 wt% and possibly Z2 an additive selected from the group consisting of alkali metal carbonate, alkaline-earth metal carbonate, alkali metal or alkaline-earth metal tripolyphosphate (Na
5 P
3 O
10 ), alkali metal or alkaline-earth metal sulfite, disulfite, or sulfate, dextrose, and complexing agent in a total amount in the range of 0.0001 to 40 wt%, wherein the components Z1 and, if applicable, Z2 in a solid and/or dry state or in a state of suspension in a solvent are brought into contact with at least one of the following compounds V in a solid and/or dry state or in a state of suspension in a solvent, wherein the compounds V are selected from the group consisting of: (a) oxides of the alkali metals lithium, sodium, potassium, rubidium, cesium, or magnesium, (b) sodium tetrahydroborate (NaBH
4 ), (c) water-free copper(II) sulfate (Cu(SO
4 )), phosphorus pentoxide, and (d) basic amino acids arginine, lysine, histidine, characterized in that the solvent for Z1, Z2 if applicable, and V is practically free of water.
