| 中文摘要 | heat capacities and thermodynamic properties of (s)-tert-butyl 1-phenylethylcarbamate |
| 英文摘要 | 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. |
