摘要: The temperature and enthalpy vs. composition diagrams of the binary system [xC3H7CO2Li+(1–x)C3H7CO2Rb], where x=mole fraction, were determined by differential scanning calorimetry (DSC). This systems displays formation two mixed salts with a 1:1 1:2, which melt incongruently at Tfus=590.5 K, ΔfusHm=11.6 kJ mol–1, congruently Tfus=614.5 ΔfusHm=20.2 respectively. phase diagram also presents an ionic liquid-crystalline in wide range: 95 K.
