| 英文摘要 | a solid complex of rare-earth compounds with alanine, [ery(ala)(4)(h2o)(8)](clo4)6 (ala=alanine), was synthesized, and a calorimetric study and thermal analysis for it was performed through adiabatic calorimetry and thermogravimetry. the low-temperature heat capacity of [ery(ala)(4)(h2o)(8)](clo4)(6) was measured with an automated adiabatic precision calorimeter over the temperature range from 78 to 377 k. a solid-solid phase transition was found between 99 and 121 k with a peak temperature at 115.78 k. the enthalpy and entropy of the phase transition was determined to be 1.957 kj mol(-1), 16.90 j mol(-1) k-1, respectively. thermal decomposition of the complex was investigated in the temperature range of 40similar to550degreesc by use of the thermogravimetric and differential thermogravimetric (tg/dtg) analysis techniques. the tg/dtg curves showed that the decomposition started from 120 and ended at 430degreesc, completed in three steps. a possible mechanism of the thermal decomposition was elucidated. |
