| 英文摘要 | the heat capacities (c (p,m)) of 2-amino-5-methylpyridine (amp) were measured by a precision automated adiabatic calorimeter over the temperature range from 80 to 398 k. a solid-liquid phase transition was found in the range from 336 to 351 k with the peak heat capacity at 350.426 k. the melting temperature (t (m)), the molar enthalpy (delta(fus) h (m) (0) ), and the molar entropy (delta(fus) s (m) (0) ) of fusion were determined to be 350.431 +/- 0.018 k, 18.108 kj mol(-1) and 51.676 j k(-1) mol(-1), respectively. the mole fraction purity of the sample used was determined to be 0.99734 through the van't hoff equation. the thermodynamic functions (h (t)-h (298.15) and s (t)-s (298.15)) were calculated. the molar energy of combustion and the standard molar enthalpy of combustion were determined, delta u (c)(c(6)h(8)n(2),cr)= -3500.15 +/- 1.51 kj mol(-1) and delta(c) h (m) (0) (c(6)h(8)n(2),cr)= -3502.64 +/- 1.51 kj mol(-1), by means of a precision oxygen-bomb combustion calorimeter at t=298.15 k. the standard molar enthalpy of formation of the crystalline compound was derived, delta(r) h (m) (0) (c(6)h(8)n(2),cr)= -1.74 +/- 0.57 kj mol(-1). |
