| 英文摘要 | isoproturon [n'-(p-cumenyl)-n,n-dimethylurea] was synthesized, and the low-temperature heat capacities were measured with a small sample precise automatic adiabatic calorimeter over the temperature range from 78 to 342 k. no thermal anomaly or phase transition was observed in this temperature range. the melting and thermal decomposition behavior of isoproturon was investigated by thermogravimetric analysis (tg) and differential scanning calorimetry (dsc). the melting point and decomposition temperature of isoproturon were determined to be 152.4 and 239.0degreesc. the molar melting enthalpy, and entropy of isoproturon, deltah(m) and deltas(m), were determined to be 21.33 and 50.13 j k-1 mol(-1), respectively. the fundamental thermodynamic functions of isoproturon relative to standard reference temperature, 298.15 k, were derived from the heat capacity data. |
