| 英文摘要 | an important solid-solid phase change heat storage material (pcm) 2-amino-2-methyl-1,3-propanediol was investigated by calorimetric methods. the molar heat capacities of the compound were measured in the temperature range from 78 to 405 k by means of a small sample automated adiabatic calorimeter. a solid-solid and solid-liquid phase transitions were found at t = 351.598 k and 380.633 k. respectively, from the experimental c(p)-t curve. the molar enthalpies and entropies of these transitions were determined to be 24.33 +/- 0.02 kj mol(-1), 69.20 +/- 0.07 j k(-1) mol(-1) for the solid-solid phase transition and 4.01 +/- 0.01 kj mol(-1), 10.52 +/- 0.01 j k(-1) mol(-1) for the solid-liquid phase transition, respectively. the thermodynamic functions (h(t)-h(298.15)) and (s(t)-s(298.15)), were derived from the heat capacity data in the temperature range of 78-405 k with an interval of 5 k. a precise oxygen-bomb combustion calorimeter was used to obtain the standard molar enthalpy of combustion and the standard molar enthalpy of formation, delta(c)h(m)(0) (c(5)h(11)no(2), cr) = ( -3326.25 +/- 0.52) kj mol(-1) and delta(f)h(m)(0) (c(5)h(11)no(2), cr) = (-213.37 +/- 0.86) kj mol(-1). dsc and tg tests were performed to investigate the solid-solid and solid-liquid phase transition behaviors and its thermostability. the results were in agreement with those obtained from heat capacity measurements, which indicated that 2-amino-2-methyl-1,3-propanediol possesses typical solid-solid phase change material characteristics, such as, suitable transition temperature, high transition enthalpy and good thermal stability.
