Read： 1224 Time：14months ago Source：Transform the World with Simplicity

Ethyl acetate is an important organic chemical raw material, which has a wide range of applications in the field of chemical production. This article will introduce the properties, production methods and main uses of ethyl acetate in detail.

1. the nature of ethyl acetate

ethyl acetate is a colorless transparent liquid with a pleasant fruity aroma. Its molecular formula is C4H8O2, and its structure is CH3COOC2H5. Ethyl acetate has a boiling point of 77.1 ° C. and a density of 0.902g/cm3, and is insoluble in water, but is miscible with organic solvents such as alcohols and ethers.

ethyl acetate has strong volatility and flammability, special attention should be paid to safety during storage and use. In addition, ethyl acetate also has a certain toxicity and irritation, long-term exposure may cause adverse effects on the human body.

2. ethyl acetate production method

ethyl acetate production method mainly has two kinds of esterification and biological method.

1. esterification method: esterification method is acetic acid and ethanol as raw materials, in the acidic catalyst under the action of esterification reaction, generating ethyl acetate and water. This method is mature and simple to operate, but it will produce a large amount of wastewater and cause some pollution to the environment.
2. biological method: biological method is the use of microorganisms or enzymes to catalyze the esterification of acetic acid and ethanol to generate ethyl acetate. The method has mild conditions and good environmental protection, but the production efficiency is low and the cost is high.

3. the use of ethyl acetate

ethyl acetate in the field of chemical production has a wide range of uses, the following list of several main aspects:

1. solvent: ethyl acetate is an excellent solvent, can be used for coatings, inks, adhesives and other production, improve product performance and quality.
2. synthetic spices: ethyl acetate can be used as an important raw material for the synthesis of spices, used in the production of a variety of fruit flavor, such as bananas, strawberries, peaches and so on.
3. Synthesis of plastics and rubber: Ethyl acetate can be used as a monomer for the synthesis of plastics and rubber for the production of polymer materials, such as vinyl acetate and polyethylene.
4. synthetic drugs: ethyl acetate is also widely used in drug synthesis, and can be used as an intermediate to prepare various drugs, such as anti-inflammatory drugs and anti-cancer drugs.

In conclusion, as an important organic chemical raw material, ethyl acetate plays an irreplaceable role in the field of chemical production. Understanding the properties, production methods and uses of ethyl acetate is of great significance for improving the production efficiency of chemical products, reducing costs and protecting the environment. In the process of using ethyl acetate, it is necessary to pay attention to safety and environmental protection, take effective measures to ensure the smooth progress of the production process, and create more value for mankind.
