Karl fischer reagent pyridine free
WebbKarl Fischer titration is a classic titration method in chemical analysis that uses coulometric or volumetric titration to determine trace amounts of water in a sample. It was invented in 1935 by the German chemist Karl … WebbThe common base used in Karl Fischer titration is pyridine, primary amines such as imidazole can also be used. ROH + SO 2 + RN => [RNH]SO 3 R The alkyl sulphite is then oxidized by iodine to an alkyl sulphate, it is this oxidation reaction which consumes water that is used for water content determination.
