一、理念依据4—甲基吡啶釜中的吡啶碱是一种有机弱碱,它在水溶液中解离常很低,用常规的酸定法不能够得到明显的终点。为了正确的测定釜残总量;作为中反应判定终点的依据,使用了滴定法。在有机溶剂中,吡啶类化合物的碱性得以突出;从而能够得到一个明显的终点。 First, the idea based on pyridine base 4 - methyl pyridine base is an organic weak base, it is often very low in aqueous solution dissociation, with conventional acid determination can not get a clear end point. In order to correctly determine the total amount of bottoms; as the basis for the determination of the end of the reaction, the use of titration. In organic solvents, the alkalinity of the pyridine compounds is outstanding; thus a clear end point can be obtained.
