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.
