摘要：
Solubilities were measured from 25 to 45 degrees C for six lithium salts (LiF, LiCl, LiBr, LiNO3, LiTFSI and LiPF6) in five pure non-aqueous solvents (ethanol, acetonitrile, dimethyl carbonate, dimethyl sulfoxide and propylene carbonate) and in a few of their binary mixtures (ethanol + DMSO, DMC + DMSO and DMC + PC). The experimental method uses a Varian inductively-coupled plasma-optical-emission spectrometer (ICP-OES). Solubilities increase with rising temperature. At a given temperature, LiNO3 shows the highest solubility in all solvents. Salt solubilities follow the order LiNO3> LiTFSI > LiBr > LiCI > LiPF6 > LiF. The dissolving abilities of the solvents are in the order ethanol > DMSO > acetonitrile > PC > DMC. Coupled with the salt's melting temperature and enthalpy of fusion, liquid-phase activity coefficients for salts were obtained from the solubility data. (C) 2018 Elsevier B.V. All rights reserved.
