六氟磷酸锂在乙腈和乙二醇二甲醚中的溶解度研究

Abstract

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.
