四苯硼酸铷在水及直链一元醇中的溶解度

THE SOLUBILITIES OF RUBIDIUM TETRAPHENYLBORATE IN WATER AND STRAIGHT-CHAIN N-ALKANOLS

在288．15～328．15K（间隔10K）下，用光度法测定了RbBPh4在纯水及8种直链一元醇中的溶解度，通过微机曲线拟合给出了RbBPh4的溶解度与直链一元醇碳原子数及温度的经验关系：lgS＝0．2347－0．4549lgn－（860．09＋341．67lgn）／T，并对NaBPh4与RbBPh4溶解度差别进行热力学分析．

Solubilities of RbBPh4 in Water, methanol, Ethanol, 1-Propanol, 1-Butanol, 1-Pentanol, 1-Hexanol, 1-Hepanol and 1-Octanol at 288.15～328. 15K have been determined by the spectrophotometry. The results can be experssed as lgS=0.2347-0.4549lgn-(860.09+341. 67lgn)/T, The differences of Solubilities of NaBPh4 and RbBPh4 are discussed.
