一价四苯硼盐在混合溶剂中热力学性质的研究(Ⅱ)—KBPh_4在(H_2O-CH_3OH)混合溶剂中的溶解度

Study on Thermodynamical Properties of Monovalent Tetraphenylborate in Mixed Solvents(Ⅱ)

用光度法测定了不同温度下 KBPh4在水及不同组成 (H2 O- CH3OH )混合溶剂中的溶解度 .实验结果表明 ,KBPh4的溶解度随温度的升高而增大 ,指定温度下 ,溶解度随混合溶剂中的甲醇 (CH3OH)物质量的分数增加而增大 .

Solubilities of KBPh 4 in Methanol\|Water Mixtures with 0,20,40,60 and 80 weight% of methanol are determined at four temperatures from 288.15K to 308.15K from absorbance of solution of KBPh 4.The change of Solubility of KBPh 4 with experimental temperatures (T) and Compositions (X) of the mixed solvents at a given temperature are discuussed on the basis of solvation theory of electrolyte solution.\;
