Mechanism and Reaction Rate of the Karl-fischer Titration Reaction Part I. Potentiometric Measurements
The react ion rate of the cou lomet r ic variant of the Karl-Fischer t i t ra t ion reac t ion (in which electrolyt ical ly generated t r i iodide is used as ox idan t instead of iodine) has been measured in methanol . The react ion is first order in water , sulfur d ioxide and t r i iodide, respectively. For pH < 5 the react ion rate cons tan t decreases logari thmical ly wi th decreasing pH. ...

متن کاملThe Basics of Karl Fischer Titration
From the reaction mechanism, it's evident that the reagent used for the titration needs to contain the following: Alcohol methanol was used originally, but in different variations of the reagent can be replaced by ethyl carbitol, methoxypropanol, ethanol, etc. Sulfur dioxide Iodine Base pyridine was used initially, but has since been replaced by imidazole, which assures a higher rate of reactio...
متن کاملThe Gas Phase Oxidation of Acetaldehyde Reaction Mechanism and Kinetics
The mechanism of the low temperature oxidation of gaseous acetaldehyde was investigated in the temperature range of 1 50-400?°C. The minor, intermediate and major products were identified and measured quantitatively by sampling directly into the ionization chamber of an MS10-C2 mass spectrometer from the reactor. The formation of H2O, CO, CO2, HCOOH, H2, HCHO, CH3COOH and CH3OH as the major pro...
