制备方法与用途

用途

1-(2-吡啶偶氮)-2-萘酚是一种过渡金属指示剂。它不仅用于络合滴定法中,还作为萃取和分光光度法测定多种过渡金属的试剂。此外,该物质也是一种染料和代谢物。

化学性质

1-(2-吡啶偶氮)-2-萘酚为橙红色无定形粉末,熔点为141℃。它溶于甲醇、乙醇、苯、醚、氯仿以及热稀碱液中,但不溶于水。其溶液在pH值超过12时呈粉红色,在弱酸性条件下则显橙红色,而在浓硫酸中会呈现紫色。与金属形成的络合物则呈现粉红色或红色。

用途

该品主要用作络合指示剂。

生产方法

1-(2-吡啶偶氮)-2-萘酚的制备过程如下:首先由2-氨基吡啶经重氮化处理后,与2-萘酚进行偶联反应。具体步骤为将无水乙醇与金属钠作用生成乙醇钠,再加入2-氨基吡啶的乙醇溶液,并通入亚硝酸乙酯蒸汽,在45至50℃条件下反应。反应结束后保温8小时,然后过滤出重氮盐并用乙醚洗涤。接着将此重氮盐加入到2-萘酚的乙醇溶液中,在同一温度下进行偶合反应6小时后过滤得到结晶体。最后,使用蒸馏水洗涤,并在乙醇中进行重结晶干燥即可获得成品。

    摘要:
    A series of azo-compounds were reduced to related aromatic amines in the presence of Fe powder and ammonium chloride. This one step protocol led to the formation of products in middle to high yields, especially when electron releasing substituted aromatic azo-compounds were reduced.

  • Selective Complexation in Three Component Cocrystals Composed of Pyrogallol[4]arene and Fluorescent Probes Pyrene and 1-(2-Pyridylazo)-2-naphthol
    作者:Constance R. Pfeiffer、Drew A. Fowler、Jerry L. Atwood
    DOI:10.1021/acs.cgd.5b00609
    日期:2015.8.5
    Cocrystals composed of a pyrogallol[4]arene molecule (one of C-propylpyrogallol[4]arene in ethanol and one of C-hexylpyrogallol[4]arene in isopropanol) and a pyrene molecule were crystallized and investigated with the aim to develop trends based on solvent and aliphatic tail length of the pyrogallol[4]arene. These new trends along with previously determined trends for the fluorescent probe 1-(2-pyridylazo)-2-naphthol (PAN), were then used to crystallize a cocrystal composed of C-hexylpyrogallol[4]arene and two fluorescent probes, pyrene and PAN. Within a two-component cocrystal of pyrene or PAN, the probe molecules are complexed in both the endo (inside the pyrogallol[4]arene bowl) and exo (outside the pyrogallol[4]arene bowl) positions. However, in the three component system, selective complexation of the probes is demonstrated whereby the PAN molecules prefer to be endo and the pyrene molecules occupy exo positions.
