一价四苯硼盐在混合溶剂中热力学性质的研究(Ⅰ)——NH_4BPh_4在(H_2O-CH_3OH)混合溶剂中溶解度的测定

Study on Thermodynamical Propeties of MonovalentTetraphenylborate in Mixed Solvents(Ⅰ) ——Determination of Solution of NH4BPh4 in Methanol Water Mixtures at from 283.15K to 318.15K

用光度法测定了ＮＨ４ＢＰｈ４在水及六个组成比例不同的（Ｈ２Ｏ－ＣＨ３ＯＨ）混合溶剂中，２８３．１５Ｋ到３０８．１５Ｋ六个实验温度下的溶解度．实验结果表明，ＮＨ４ＢＰｈ４的溶解度随温度的升高而增大．指定实验温度下。

Solubilities of NH4BPh4 in Methanol Water Mixtures with 0,10,20,30,40,50,and 60 weight% of methanol have been determined at six temperatures from 283.15K to 308.15K from absorbance measurement of solution of NH4BPh4.The experimental results can be expressed as:lnS=3.134-3561/T+7.016×10-2Wt% The change of Solubilities of NH4Bph4 with experimental temperatures (T) and Compositions(X) of the mixed solvents at a given temperature have been discussed on the basis of solvation theory of electralyte solution 
