英文摘要The constant volume energy of combustion of crystalline 3,5-di-tert-butylsalicylic acid (t-BSA) in oxygen at 298.15 K was determined using combustion calorimeter to be -8292.57 +/- 2.51 kJ mol(-1). The standard molar enthalpies of combustion and formation of 3,5-di-tert-butylsalicylic acid were derived, at T = 298.15 K, Delta(c)H(m)(Theta) = -8302.48 +/- 2.51 kJ mol(-1) and Delta(f)H(m)(Theta) = -744.30 +/- 3.21 kJ mol(-1), respectively. The heat capacities of the compound were measured with an adiabatic calorimeter over the temperature range from 79 to 351 K. No indication of any phase transition or thermal anomaly was observed in this temperature range. The fusion and evaporation behavior of the compound were examined by thermogravimetry (TG). differential thermal analysis (DTA) and differential scanning calorimetry (DSC). The molar enthalpy and entropy of fusion. Delta(fus)H(m)(Theta) and Delta(fus)S(m)(Theta), at T = 437.5 K, were determined to be 22.92 +/- 0.55 kJ mol(-1) and 139.4 +/- 3.3 J mol(-1) K-1, respectively: and the molar enthalpy and entropy of evaporation, Delta(vap)H(m)(Theta) and Delta(vap)S(m)(Theta), at T = 477.5 K, were obtained as 83.88 +/- 2.1 kJ mol(-1) and 341.7 +/- 8.4 J mol(-1) K-1, respectively.
