| 摘 要： | 用平衡法测定了-10～40 ℃下六氟磷酸锂在乙腈中的溶解度及其0～50 ℃下在乙二醇二甲醚中的溶解度。采用简化的二参数模型对六氟磷酸锂的溶解度数据进行关联，拟合出了六氟磷酸锂溶解度的对数与绝对温度倒数的一元线性方程，用该方程可测算不同温度下六氟磷酸锂在2种溶剂中的溶解度，平均相对误差均小于3%。该研究结果可为六氟磷酸锂的结晶提纯提供相关参数。

| Abstract: | Solubilities of lithium hexafluorophosphate in acetonitrile at-10～40 ℃ and in 1,2-dimethoxyethane (DME) at 0～50 ℃ were measured by static equilibrium method,respectively.A linear equation of natural logarithm for the solubility of lithium hexafluorophosphate versus the reciprocal of the absolute temperature was correlated from the solubility data with a simplified two-parameter model. Equation can be used to predict the solubility of lithium hexafluorophosphate in the two kinds of solvents at different temperatures and the relative average errors between predicted results and experimental values were less than 3%.Experimental results could provide related parameters for the recrystallization and purification of lithium hexafluorophosphate. |
