In this paper, a microsystem integrated with infrared thermography is developed to measure the kinetics of fast exothermic reactions. The hydrolysis of ethyl acetate is chosen as the model reaction to verify the technique. The activation energy of this reaction is successfully obtained, which agrees well with the literature value. Except for the general method of collecting data from several typical points of the infrared radiation (IR) picture, a strategy called image analysis is applied to obtain the temperature profiles along the reactor by collecting data from the whole IR picture. With the image analysis, this system can generate time-series kinetic data in a single experiment, which is usually challenging for a continuous flow system. The reaction enthalpy of classic neutralization reaction and kinetic parameter of hydrolysis are determined again using the image analysis, showing fewer deviations from literature values. The image analysis technique could provide much more reliable and accurate results with higher efficiency.

在本文中，开发了一种与红外热像仪集成的微系统，用于测量快速放热反应的动力学。选择乙酸乙酯的水解作为模型反应以验证该技术。成功获得了该反应的活化能，与文献报道值相吻合。除了从红外辐射（IR）图像的几个典型点收集数据的一般方法之外，还采用一种称为图像分析的策略，通过从整个IR图像中收集数据来获得反应堆的温度分布。通过图像分析，该系统可以在单个实验中生成时间序列动力学数据，这对于连续流系统通常具有挑战性。使用图像分析再次确定了经典中和反应的反应焓和水解动力学参数，与文献值的偏差较小。图像分析技术可以以更高的效率提供更加可靠和准确的结果。
