甲(月朁)是偶氮染料中的一个重要分支,它们与金属离子所形成的络合物有很强的颜色。Friese于1875年合成了第一个甲(月朁)化合物,为了改善甲(月朁)金属螯合物的水溶性,Wizinger和Biro于1949年合成了一系列端苯环邻位酸性取代基的甲(月朁)衍生物,这些取代基都显示了特殊的螯合性,他们的工作对甲(月朁)化学的发展起了很大的推动作用。长期以来在分析化学上得到广泛应用的甲(月朁)衍生物有打萨腙,二苯卡巴腙,锌试剂等,这些试剂可用来测定Pd,Cd,Pt,Hg,Ag等元素,到目前为止,带胂酸基的甲(月朁)衍生物均系3-氰基甲(月朁)衍生物。自偶
A (moon cake) is an important branch of azo dyes, they formed with the metal ion complexes have a strong color. Friese synthesized the first A (moon cake) compound in 1875. In order to improve the water solubility of the A (moon cake) metal chelate, Wizinger and Biro in 1949 synthesized a series of terminal phenyl ring ortho acid substituents A (moon cake) derivatives, these substituents have shown a special chelating, their work on the development of a (moon) chemical played a significant role in promoting. For a long time in analytical chemistry has been widely used in A (moon cake) derivatives are dozen hydrazone, diphenylcarbazone, zinc reagent, these reagents can be used to determine the Pd, Cd, Pt, Hg, Ag and other elements, up to now So far, aracetic acid-based derivatives of the A (canthal) are all 3-cyanomethyl (cantharidin) derivatives.
