| 摘 要： | 用4－磺基邻苯二甲酸三铵盐与尿素在金属锑的催化下反应，合成了4，4′，4″,4″′-四磺酸基酞菁（H2TSPc)。用分光光度法对该化合物在溶液中的性质进行了研究。研究发现，溶剂、H2TSPc的浓度、溶液的pH，均对化合物的吸收光谱产生影响。本文对H2TSPc在水溶液中的存在形式进行了研究，并对溶剂性质、介质酸度等因素对H2TSPc在水溶液中的存在形式的影响作用及其机理作了探讨。

| Abstract: | Metal-free tetrasulfophthalocyanine was synthesized by the reaction of triammonium salt of 4-sulfophalic acid with urea,using antimony powder as catalyst.The aggregation of this compound in aqueous and aqueous alcoholic solutions(MeOH,EtOH,ArOH) has been studied by electronic absorption spectra.The result shows that several factors such as the composition of the solvent,the acidity of solution,influence the extent of the aggregation.The dimerisation constant (K d) of the titled compound in different solvents is reported. |
