摘要： 作者曾报道用溶质蒸气循环方式制备液态芳烃的饱和溶液,测出苯、甲苯、二甲苯、卤代苯等液态芳烃在水和硝酸银体系中的溶解度,并计算了上述芳烃与Ag+配合物的形成常数。具有C=C双键的许多固态芳烃也象液态芳烃一样可与银离子形成配合物,我们设计了溶质蒸气循环方式制备固态芳烃的装置,该法的最大特点是固态溶质和溶剂不直接接触,可以避免固态溶质颗粒在溶剂中的分散和容器壁上的吸附现象,因此用本法测定的溶解度和配合物的形成常数数据可靠、精确。

Abstract: The preparation of saturated liquid aromatic hydrocarbons by circulation of solute vapour and the solubility of liquid aromatic hydrocarbons in silver nitrate solution are reported. Complex formation constants between those liquid aromatic hydrocarbons and silver ion were calculated from solubilities.The preparation apparatus was designed for preparing saturated vapour of solid aromatic hydrocarbons and we determined the solubilities of naphthalene, phenanthrene, anthracene biphenyl, p-dichlorobenzene in silver nitrate solution and calculated the complex formation costants between those substances and silver ion.

Key words: Solid aromatic hydrocarbons, Silver ion, Circulation of solute vapour, Complex forma-tion constants
