Application Memo Water Content of Ether (2) [Long-chain Ether] IndustryPetrochemicalsInstrumentKarl Fischer Moisture TitratorMeasurement methodVolumetric titrationStandardsJIS K 0113， ASTM E 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 long-chain ether by directmethod of KF titration according to JIS K 0113-2005 as quoted below. The long-chain ethersin general are hard to dissolve in methanol. Therefore， we use KET solvent mixed withchloroform. The test samples we measured according to the above method are as follows：Allyl glycidyl ether/Propylene oxide/Vinyl oxide 2. Apparatus Main unit Karl Fischer moisture titration volumetric system Electrode Twin Platinum Electrode 3. Reagents Titrant KEMAQUA TR-3Solvent KEMAQUA Solvent KET for Ketone 4. Example 一Measurement results- Sample name Water content mg % Allyl glycidyl ether 4.07 0.079 Propylene oxide 2.05 0.026 Vinyl oxide 3.00 0.016 Please feel free to contact us for any further information.
