| 英文摘要 | the low-temperature heat capacities of 1-hexadecanol have been measured with an automatic adiabatic calorimeter over the temperature range from 80 to 370 k. a solid-liquid phase transition was observed at t-m=322.225 +/- 0.002 k and the molar enthalpy and entropy of fusion were determined to be 57.743 +/- 0.008 kj mol(-1) and 179.19 +/- 0.04 j k-1 mol(-1), respectively. the purity, the real melting point (t-1) and the ideal melting point without any impurity or absolutely purity (to) of the sample under investigation were determined to be 99.162 mol%, 322.21 and 322.34 k, respectively, by fractional melting method. according to the polynomial equation of heat capacity and thermodynamic relationship, the thermodynamic functions of the compound relative to the reference temperature 298.15 k were calculated in the temperature ranges of 80 to 370 k with an interval of 5 k. in addition, further researches of thermal properties for this compound were carried out by means of tg/dtg. |
