英文摘要: Heat capacity C-p.m of 1-docosanol was precisely measured in the temperature range from 78 to 400 K by means of an automated adiabatic calorimeter. The dependence of heat capacity on the temperature was fitted to polynomial equations with least square method. The melting temperature, molar enthalpy, and molar entropy of fusion were determined to be 340.844 K, 85.07 kJ center dot mol(-1), and 249.6 J center dot K-1 center dot mol(-1), respectively. The thermodynamic functions, [H-1-H-298.15 and [S-T-S-298.15], were derived from the thermodynamic equations in the temperature range from 80 to 400 K with an interval of 5 K. The thermostability of the compound was further investigated by DSC and TG techniques from 400 to 900 K.
