Differential Scanning Calorimetric Study of Low Melting Organic Chlorogallate Systems.

摘要

The thermal stabilities of mixtures of Ga2C16 with 1-butylpyridinium chloride (BPC) and 1-methyl-3-ethylimidazolium chloride (MEIC) have been investigated in the temperature range -65 to +125 C. Solid-liquid transition temperatures along with enthalpies of fusion or glass transition data, determined by differential scanning calorimetry, are reported. MEIC based chlorogallate melts are found to possess lower phase transition temperatures than the corresponding BPC based melts. The liquidus range at room temperatures for the MEIC based chlorogallate system extends from mole fraction GaC13, N 0.3 = 0.8. Reprints. (aw)
