| 英文摘要 | adonitol was investigated by adiabatic calorimetry (ac), differential scanning calorimetry (dsc), thermogravity analysis (tga) and oxygen-bomb combustion calorimetry. the heat capacity was precisely measured in the temperature range from 78 to 400 k by means of a small sample automated adiabatic calorimeter. the melting temperature, the molar enthalpy and entropy of this transition were determined to be t=369.08 +/- 0.45 k. 36.42 +/- 0.18 kj mol(-1) and 98.68 +/- 0.49 jk(-1) mol(-1) respectively from the experimental c(p)-t curve. the thermodynamic functions [h(t)(0) - h(298.15)(0)] and [s(t)(0) - s(298.15)(0)] were derived from the heat capacity data with an interval of 5 k. the standard molar enthalpy of combustion and formation of the compound have been determined to be delta(c)h(m)(0), (c(5)h(12)o(5)center dot cr)=(-2562.4+/-1.3)kj mol(-1) and delta(c)h(m)(0) (c(5)h(12)o(5).cr)=(-1120.1+/-1.5)kj mol(-1) respectively by means of a precision oxygen-bomb combustion calorimeter at t=298.15 k. the thermostability of the compound was further studied by dsc and tga measurements.
