Tetrabutylammonium butyrate ハイドレートの熱物性測定

抄録

This paper reports the phase equilibrium temperature and dissociation heat of tetrabutylammonium butyrate (TBABu) hydrate. TBABu hydrate is a type of ionic semiclathrate hydrates. This hydrate could potentially be used as thermal energy storage materials. The phase equilibrium temperature was measured by stepwise temperature increasing procedure. The temperature – composition phase diagram of the TBABu hydrate was determined in the mass fractions from 0.20 to 0.40. The highest equilibrium temperature of TBABu hydrate was 15.3 °C at the mass fraction 0.40. On the dissociation heat of DSC measurements, the largest dissociation heat was 172 kJ/kg at the mass fraction 0.40.
