英文摘要low-temperature heat capacities of the 9-fluorenemethanol (c14h12o) have been precisely measured with a small sample automatic adiabatic calorimeter over the temperature range between t = 78 k and t = 390 k. the solid-liquid phase transition of the compound has been observed to be t-fus = (376.567 +/- 0.012) k from the heat-capacity measurements. the molar enthalpy and entropy of the melting of the substance were determined to be delta(fus)h(m) = (26.273 +/- 0.013) kj (.) mol(-1) and delta(fus)s(m) = (69.770 +/- 0.035) j (.) k-1 (.) mol(-1). the experimental values of molar heat capacities in solid and liquid regions have been fitted to two polynomial equations by the least squares method. the constant-volume energy and standard molar enthalpy of combustion of the compound have been determined, delta(c)u(c14h12o, s) = -(7125.56 +/- 4.62) kj (.) mol(-1) and delta(c)h(m)degrees(c14h12o, s) = -(7131.76 +/- 4.62) kj (.) mol(-1), by means of a homemade precision oxygen-bomb combustion calorimeter at t = (298.15 +/- 0.001) k. the standard molar enthalpy of formation of the compound has been derived, delta(f)h(m)degrees (c14h12o, s) = -(92.36 +/- 0.97) kj (.) mol(-1), from the standard molar enthalpy of combustion of the compound in combination with other auxiliary thermodynamic quantities through a hess thermochemical cycle.
