绝热量热技术的广泛应用促进了绝热动力学研究的发展.至今为止,绝热动力学的研究仍是以Townsend和Tou在1980年提出的绝热动力学方程为基础.他们利用反应物浓度与温度的关系建立动力学模型,从而求得了反应的活化能.但这种方法在反应体系的温度效应不明显时的应用,就受到很大的限制.因此,本文通过建立用压力表示的动力学方程,充分利用绝热量热中的压力数据,提出了一种计算反应活化能的新方法.同时用这种方法计算了过氧化二叔丁基和2-甲基-5-硝基苯磺酸的绝热分解活化能值,并与文献值和其他计算方法所得结果进行了比较.
The advent of adiabatic calorimetry is widely used to promote the development of adiabatic kinetics, and so far the adiabatic kinetics has been based on the adiabatic kinetic equations proposed by Townsend and Tou in 1980. They use the reactant concentration and temperature The relationship between the establishment of kinetic model, and thus obtained the activation energy of the reaction, but this method in the reaction system when the temperature effect is not obvious when the application is greatly restricted.Therefore, by establishing a dynamic equation with pressure, Taking full advantage of the pressure data in adiabatic calorimetry, a new method for calculating the activation energy of reaction was proposed, and the thermal insulation of di-tert-butyl peroxide and 2-methyl-5-nitrobenzene sulfonic acid The activation energy is decomposed and compared with the results obtained from literature and other calculations.
