英文摘要the rare-earth perchlorate complex compound with dl-α-glycin was synthesized. its structure was characterized as [pr-2 (dl-α-gly)(6)(h2o)(4)] (clo4)(6) • 5h(2)o by tg, dta and chemical analysis, and the purity was 99.63%. the melting point analysis experiment indicates that the complex has no stable melting point. the heat capacity of the complex was measured by a high-precise fully-automated adiabatic calorimeter from 79 to 371 k. no obvious abnormal heat capacity was observed within this low temperature range. the thermal decomposition temperature range of the complex was near 333 k. its decomposition temperature, decomposition enthalpy and entropy were 320.010 k, 40.714 kj/mol and 127.227 j/molk, respectively. the polynomial equation of heat capacity of this compound was simulated by the computer within the temperature range of 78.939 ∼ 301.295 k. the standard enthalpy of formation was -8022.802 kj/mol measured by isoperable reaction calorimeter at 298.15 k.
