Die Zersetzung saurer, methanolischer Karl-Fischer-L�sungen

Autor: Konrad Beckenkamp, Wolfgang Fischer

Publikováno v: Journal f�r Praktische Chemie/Chemiker-Zeitung. 340:58-61

The Decomposition of Acidic Karl Fischer Reagent in Methanol The reaction between sulfur dioxide and iodine in methanol is started by traces of water in the solvent. Hydrogen iodide is formed and reacts with methanol to produce more water until all i
