摘要
本研究采用平衡法测试了硫酸钠、硫代硫酸钠、硫氰酸钠在甲醇中的溶解度并系统考察了其受温度影响的规律。结果表明,硫氰酸钠在甲醇中溶解度很高,受温度影响很大,随温度升高以二次幂函数形式显著升高;硫代硫酸钠在甲醇中溶解度很低,比硫氰酸钠溶解度低约二个数量级,受温度影响较大,随温度升高指数降低;硫酸钠在甲醇中溶解度极低,比硫代硫酸钠的溶解度低约一个数量,受温度影响很小,随温度升高略微线性下降。
In this study,the solubility of sodium sulfate,sodium thiosulfate and sodium thiocyanate in methanol was tested by the equilibrium method,and their temperature dependence was systematically investigated.The results show that the solubility of sodium thiocyanate in methanol is very high,greatly affected by temperature,and increases significantly with the increase of temperature in the form of a quadratic power function;the solubility of sodium thiosulfate in methanol is very low,which is about two orders of magnitude lower than that of sodium thiocyanate,and is greatly affected by temperature,and decreases exponentially with the increase of temperature.The solubility of sodium sulfate in methanol is very low,about one order of magnitude lower than that of sodium thiosulfate,and is affected by temperature very little,and decreases slightly linearly with the increase of temperature.
