Description

Technical Field

[0001] The utility model relates to the field of esterification devices, in particular to an esterification device. Background Art

[0002] Esterification is a reaction in which alcohol and acid react to produce ester and water. Esterification is a reversible reaction. Generally, as the generated water accumulates to a certain concentration, the forward and reverse reactions reach equilibrium and the reaction is not complete. The prior art uses a method of removing the generated water and reducing the concentration of water in the reaction product to allow the reaction to continue. Traditional industrial esterification devices generally add a water-carrying agent to the reaction system, evaporate the water-carrying agent and water together, separate in a distillation tower, condense in a condenser, and then enter a water separator for stratified dehydration. The dehydrated water-carrying agent returns to the reaction system. In this process, the water and the water-carrying agent in the water separator are slowly separated due to their different polarities, which is inefficient and poor in practicality.
