[0002] In the chemical industry, esterification is a very important organic synthesis reaction, which is widely used in the production of various ester compounds, such as in coatings, plastics, fragrances, medicines and many other industries, which plays a key role, for example, through the esterification reaction of carboxylic acid and alcohol, acrylate monomers used in coatings can be synthesized, and some ester compounds used as intermediates in the synthesis of drugs in the pharmaceutical industry, etc.

[0003] In the esterification reaction process, triethylamine as an acid-binding agent reacts with the acid generated in the reaction to form triethylamine hydrochloride. If a large amount of triethylamine hydrochloride is directly discarded, it not only wastes resources and increases production costs, but also may have a certain pressure on the environment from the perspective of environmental protection, because these chemicals may pollute the soil, water and other environmental media if they are randomly discharged. Therefore, recycling and processing triethylamine hydrochloride and converting it back to triethylamine for esterification reaction has significant economic and environmental significance, which prompts researchers and chemical practitioners to develop special recycling and processing devices and supporting esterification reaction devices to realize the recycling of triethylamine and optimize the entire esterification reaction process.
