Application Memo Water Content of Ether (3) [Ethyl Vinyl Ether] Industry Petrochemicals Instrument Karl Fischer Moisture Titrator Measurement method Volumetric titration Standards JIS K 0113， ASTME 203. ISO 760 1.Overview Moisture titration using Karl Fischer reagent is popularly practiced water determinationworldwide as the most reliable method. The procedure is adopted in many official standards astest method specified as in ISO， ASTM and JIS， etc. Here in this application note， we measure water content of ethyl vinyl ether by directmethod of KF titration according to JIS K 0113-2005 as quoted below. Ethyl vinyl ether is hard to dissolve in commercially sold extracting medium KET.Therefore， we use KET solvent mixed with chloroform by even ratio 1 to 1. 2. Apparatus Main unit Karl Fischer moisture titration volumetric system Electrode Twin Platinum Electrode 3. Reagents Titrant KEMAQUA TR-3 KEMAQUA Solvent KET for Ketone Solvent Chloroform 4.Example -Measurement results- Sample name Water content mg % Ethyl vinyl ether 0.54 0.062 Please feel free to contact us for any further information.
