二安替比林基溴代苯基甲烷的合成及其分析应用的研究

Study on synthesis of diantipyrylbromophenylmethanes and their analytical application

合成了ＤＡｏＢＭ、ＤＡｍＢＭ、ＤＡｐＢＭ３个二安替比林甲烷芳香族衍生物，其中ＤＡｏＢＭ和ＤＡｍＢＭ为首次合成。研究了在Ｈ３ＰＯ４介质中和Ｍｎ（Ⅱ）存在下其与Ｃｒ（Ⅵ）、Ｖ（Ⅴ）、Ｃｅ（Ⅳ）、Ｍｎ（Ⅶ）的显色反应。开发了几个试剂的应用体系，显示了良好的应用前景。

Two new aromatic derivatives of diantipyrylmethane were synthesizedThey are diantipyryl(m-bromo)phenylmethane (DAmBM) and diantipyryl(o-bromo)phenylmethane (DAoBM)According to the literature,diantipyryl(p-bromo)phenylmethane was synthesized tooThe color reaction of the above mentioned reagents with Ce(Ⅳ),V(Ⅴ),Cr(Ⅵ) and Mn(Ⅶ) in the presence of H_3PO_4 and Mn(Ⅱ) was studiedApplication of some of these systems were proposedThese methods appear to have a bright future
