ethyl acetate process

How is ethanol acetate synthesized?
Ethyl acetate is synthesized in industry mainly via the classic Fischer esterification reaction of ethanol and acetic acid. This mixture converts to the ester in about 65% yield at room temperature: The reaction can be accelerated by acid catalysis and the equilibrium can be shifted to the right by removal of water.
How is ethyl acetate separated from acetic acid?
The acetic acid produced in the oxidation is absorbed by the excess liquid ethanol, which esterifies to ethyl acetate. Ethyl acetate and water are removed from the process for separation of the ethyl acetate. The oxidation portion of process is preferred with a metallic oxidation catalyst on a hydrophobic support.
What is the design and control of ethyl acetate production plant?
In this study, the design and control of ethyl acetate production plant has been investigated. The proposed design consists of a continuous-stirred tank reactor and two distillation columns. Ethanol reacts with acetic acid and gives ethyl acetate and water.
How many reactions are involved in ethyl acetate synthesis?
Five overall reactions between the reactants leading to the formation of the main products can be identified for the ethyl acetate synthesis by direct addition as visualized in Scheme 1. Reactions r 1, r 2 and r 3 are direct additions of acetic acid, water and ethanol to ethylene and yield ethyl acetate, ethanol and diethyl ether respectively.
