摘要
利用Batch型热导式热量计测定了N-溴代丁二酰亚胺(NBS)氧化异丙醇反应的热谱曲线,并分别利用简单级数反应和连续一级反应热动力学特征对比参量法的数学模型计算了反应的动力学参数,计算结果表明:利用连续一级反应热动力学研究法处理得到的动力学参数与文献通过碘量法的测定值是吻合的,因此,在质子性溶剂中的NBS氧化异丙醇反应遵从连续一级反应的动力学规律。
The thermoanalytical curves for the oxidation of isopropanol by NBS in 50% (V/V) CH3COOH - H2O when isopropanol is the excessive reactant have been measured in a batch conduction calorimeter, and the kinetic parameters have been determined by using the thermokinetic models of the time parameter method for simple and consecutive first order reaction respectively. The experimental results indicate that the kinetic parameters calculated by the time parameter method for consecutive first order reaction are in agreement with those from literature. Therefore, the dynamic behavior of the oxidation reaction of isopropanol by NBS in protonic solvent can be considered to conform to the kinetic law of the consecutive reacions.
