英文摘要Heat capacities and thermodynamic properties of (S)-tert-butyl 1-phenylethylcarbamate; An N-tert-butyloxycarbonylated organic synthesis intermediate, (S)-tert-butyl 1-phenylethylcarbamate, was prepared and investigated by means of differential scanning calorimetry (DSC) and thermogravimetry (TG). The molar heat capacities of (S)-tert-butyl 1-phenylethylcarbamate were precisely determined by means of adiabatic calorimetry over the temperature range of 80-380 K. There was a solid-liquid phase transition exhibited during the heating process with the melting point of 359.53 K. The molar enthalpy and entropy of this transition were determined to be 29.73 kJ mol(-1) and 82.68 J K(-1) mol(-1) based on the experimental C (p)-T curve, respectively. The thermodynamic functions, and were calculated from the heat capacity data in the temperature range of 80-380 K with an interval of 5 K. TG experiment showed that the pyrolysis of the compound was started at the temperature of 385 K and terminated at 510 K within one step.
