Reactive distillation of ethyl acetate
The technology of chemical industry is related to the national economy and people's livelihood. Among them, the method of reactive distillation of ethyl acetate is the most important in the industry.

Ethyl acetate has a wide range of uses and is indispensable in many fields such as flavors and solvents. Its preparation method, reactive distillation has unique advantages.

Reactive distillation, the separation of chemical reaction and distillation is fused in one tower. In the tower, the reactants are separated while reacting, which not only promotes the process of the reaction, but also improves the purity of the product. Using acetic acid and ethanol as raw materials, under the action of catalysts, ethyl acetate and water are formed. This reaction is reversible. However, in the reaction distillation column, due to the timely separation of the products, the equilibrium continues to shift to the right, and the reaction efficiency is greatly increased.

The structure of the column is quite delicate. The light components at the top of the tower are enriched, and the recombinant components of the tower are converged. The reaction area is reasonably set to make the reaction and separation go together synergistically. During operation, parameters such as temperature, pressure, and reflux ratio need to be carefully controlled. If the temperature is too high or too low, it will affect the reaction rate and product distribution; the change of pressure is related to the phase equilibrium of the system; the size of the reflux ratio affects the purity and energy consumption of the product.

The beauty of this technology lies not only in the efficient preparation of ethyl acetate, but also Compared with the traditional method of reaction first and then separation, it is a good policy to reduce equipment investment, shorten the process flow, reduce costs and increase efficiency in the chemical industry.

Therefore, making good use of the reactive distillation of ethyl acetate can contribute to the development of the chemical industry, contribute to economic prosperity and benefit society.
