一、原理(一)费歇尔滴定原理1935年卡尔·费歇尔(Karl Fischer)提出了应用非水溶液试剂测定水分的新方法,一般称为费歇尔滴定法。此滴定法不仅可用于准确地测定化合物中微量水分,而且可用以测定有机化合物的含量。费歇尔滴定用于有机化合物的测定主要根据化合物与盐酸羟氨作用或在催化剂溶液中进行酰化时产生水或消耗水的反应,而用费歇尔试剂测定所产生或消耗的水分以计算其含量。
First, the principle (A) Fischer titration principle In 1935, Karl Fischer (Karl Fischer) proposed a new method for determination of moisture using non-aqueous reagents, commonly known as Fischer titration. This titration method can not only be used to accurately measure trace moisture in compounds, but also can be used to determine the content of organic compounds. Fischer titration is used for the determination of organic compounds mainly based on the reaction of the compound with hydroxylamine hydrochloride or the reaction of generating water or consumed water when acylation is carried out in a catalyst solution while the generated or consumed moisture is measured with a Fischer reagent to calculate Its content.
