【摘要】 用滴定量热法分别建立了满定期和停满反应期一级反应热动力学的数学模型．根据这两种模型，均可由一次实验的滴定量热曲线同时解析出一级反应的速率常数（k1）和摩尔反应治（△rHm）．用液定量热法研究了去离子水溶剂中乙酸乙酯皂化反应的热动力学，实验结果验证了本文用滴定量热法研究一级反应热动力学的运用性．更多还原

【Abstract】 The mathematical models for thermokinetics of first-order reactions in titration pe-riod and in the stopped-titration reaction period have been suggested, respectively, by titrationcalorimetry. By analyzing the titration calorimetric curve of one experiment of a reaction, thesetwo models can be used to calculate the first-order rate constant (k1) and the molar enthalpy(△rHm) of the reaction. Thermokinetics of the saponification of ethyl acetate in doubly distilledwater was studied by titration calorimetry. The reliability of this titration calorimetric methodfor studying thermokinetics of first-order reactions has been verified by the erperimental resultsobtained.更多还原
