文摘

In the present research, the temperature dependence of heat capacity \( C_{{\text{p}\text{,m}}}^{\text{o}} = f\left( T \right) \) of α-terpineol has been measured for the first time between T = (6 and 345) K in the precision adiabatic vacuum calorimeter. The temperature and enthalpy of fusion of α-terpineol and the total mole fraction of impurities have been determined. The experimental results have been used to calculate the standard thermodynamic functions \( C_{{\text {p}\text{,m}}}^{\text{o}} /R,\;\Delta_{\text{0}}^{\text {T}} H_{\text{m}}^{\text{o}} /RT,\Delta_{\text{0}}^{\text {T}} S_{\text{m}}^{\text{o}} /R\;{\text{and}}\;\Phi_{\text{m}}^{\text{o}} /R = \Delta_{\text{0}}^{\text T} S_{\text{m}}^{\text{o}} /R{-}\Delta_{\text{0}}^{\text T} H_{\text{m}}^{\text{o}} /RT \) (where R is the universal gas constant) of α-terpineol over the range from T → (0 to 345) K. The standard entropy of formation of the compound (cr) under study at T = 298.15 K has been calculated. Keywords α-Terpineol Low-temperature calorimetry Molar heat capacity Entropy
