Read： 699 Time：18months ago Source：Transform the World with Simplicity

Ethyl acetate is a common ester organic compound, which is commonly used in solvents, coatings, plastics and other industrial fields. Its production process and preparation methods are diversified, which we will describe in detail below. The production process of

ethyl acetate mainly includes ethyl acetate method, ethanol alkylation method and alkyd ester exchange method. Among them, the ethyl acetate method is the most common and economical method. The raw materials of

ethyl acetate method mainly include acetic acid and ethanol, and the reaction conditions are dehydration esterification reaction under the action of catalyst. Molten salt catalyst and sulfuric acid catalyst is one of the commonly used catalysts. The specific operation procedure is as follows:
Acetic acid and ethanol are
added into the reaction kettle, and the required catalyst is added. Then, the reaction temperature was raised to about 80-90 ° C. by heating the reaction vessel while stirring with the stirrer turned on. A certain amount of refluxing liquid nitrogen is added during the reaction to ensure the stability of the reaction temperature. After completion of the reaction, heating was stopped and water bath cooling was performed. Finally, the reaction product, ethyl acetate, was purified by distillation under reduced pressure.

In addition to ethyl acetate, ethanol alkylation and alkyd transesterification are also effective methods for the preparation of ethyl acetate. Among them, the ethanol alkylation method is a process of reacting ethanol and formic acid catalyst to generate ethyl acetate, and the alkyd ester exchange law is a process of ethyl acetate and ethanol exchange reaction to obtain ethyl acetate.
the production process and preparation methods of ethyl
acetate are varied, with the continuous progress of science and technology and the continuous improvement of the process, its production will be more efficient and environmentally friendly.
