TITRANT FOR BACK TITRATION METHOD FOR KARL FISCHER MOISTURE MEASUREMENT

摘要

PROBLEM TO BE SOLVED: To provide a titrant for back titration method having weak hygroscopicity and stable titer, not obstructing the normal progress of a KF reaction, having low inflammability, and easy in daily management.;SOLUTION: In this titrant for back titration method used for Karl Fischer moisture measurement, a solvent is at least one kind selected from a monoalkyl carbonate (especially propylene carbonate), a dialkyl carbonate (especially diethyl carbonate), N-methyl-2-pyrolidone, or a mono-or dialkyl ether of an alkylene or a dialkylene glycol.;COPYRIGHT: (C)2000,JPO
