摘要：

化学反应常常伴随能量变化，为获取能量变化信息，将手机热成像仪FLIR One Pro与智能手机组成具有热成像功能的装置用于化学实验数据采集和处理。对毛细管法测定萘的熔点、蒸馏法测定乙醇的沸点及浓硫酸与纸的脱水反应实验中温度动态分布进行可视化观察。得到了不同反应中温度随时间变化的直观图像，图像颜色变化表征了不同反应过程的能量变化信息。这种装置能快速、准确、无接触获取体系温度，能对肉眼不可见的温度变化进行直接观察，根据颜色的变化还能显示反应的剧烈程度。

关键词: 热成像技术, 温度可视化, 热图像

Abstract:

Chemical reaction is often associated with the energy changes. The chemical laboratory data of energy changes was recorded on the thermal imaging device made by the phone thermal imaging plug-in FLIR One Pro and smart mobile phone component. The dynamic temperature distribution in the capillary method for the determination of the melting point of naphthalene, the distillation method for the determination of the boiling point of ethanol and the dehydration reaction of concentrated sulfuric acid with paper were visualized. The images of temperature change with time in different reactions were obtained, and the color change of the images represented the energy change information of different reaction processes. This device can quickly, accurately obtain the system temperature without contact, and provides a visualization of the temperature changes invisible to the human eyes.
