MERCURIC ACETATE

A new method for determining the iodine value of oil and fat is reported . The method only requires to add the catalyst mercuric acetate in the process of determination without changing the operational steps of the Hanus method .

报道了一种测定油脂碘值的新方法，不改变Hanus法操作步骤，只需在测定过程中加入催化剂醋酸汞。

By measuring the water content , pH value and hydroxyl value of the macromonomer , determing the reaction conditions of the method of addition of mercuric acetate , derive accurate determination of methods of analysis double value in ether monomers .

通过测定大单体的含水量，pH值，羟值对测定双键值的影响，并确定乙酸汞加成法的反应条件，得出准确测定醚类单体双键值的分析方法。

The electron population on the imino-nitrogen atom is the largest , thus the mercuric acetate should first coordinate with imino-nitrogen atom in the process of the reaction and then subsequent electrophilic substitution takes place in the ortho-position of the .

分子中亚胺氮原子的电荷密度最大，在汞化反应过程中，亚胺氮原子首先与醋酸汞配位，然后再进行邻位亲电进攻，生成邻位汞化产物；
