本文合成了三醋酸铀酰锂、钠、钾、铷和铯。锂络合物带两个结晶水,其余为无水络合物。测定了它们的比重、介电常数、折光率和在水中的溶解度。计算了它们的克分子极化度、克分子折射度和离子化程度。研究了这些络合物极化度对溶解度的影响,它们的变化规律是按钠、钾、铷和铯络合物依次增加,带两个结晶水的锂络合物有较高的极化度,因此它的溶解度也较高。
In this paper, three uranyl acetate lithium, sodium, potassium, rubidium and cesium were synthesized. Lithium complex with two crystal water, the rest is anhydrous complex. Their specific gravity, dielectric constant, refractive index and solubility in water were measured. Their degree of molecular polarizability, molecular refractive index and degree of ionization were calculated. The effects of the polarizabilities of these complexes on solubility were investigated. The variation regularity of these complexes was in the order of sodium, potassium, rubidium and cesium complexes. The lithium complexes with two crystal water had higher polarizabilities , So its solubility is also higher.
