Ethyl acetate NEW

Ethyl acetate, also known as ethyl acetate, is a compound produced when the hydroxyl group in acetic acid is replaced by the ethoxy group, and the structure is simply CH3COOCH2CH3. Pure ethyl acetate is a colorless, transparent and aromatic liquid, melting point: -83.6 ° C, boiling point: 77.06 ° C, relative density (water =1) : 0.894-0.898, relative vapor density (air =1) : 3.04, with a strong ether-like odor, clear spirit, microfruity aroma of wine, easy to spread, not lasting. Slightly soluble in water, soluble in alcohol, ketone, ether, chloroform and other organic solvents. Ethyl acetate is a fine chemical product with a wide range of uses. It has excellent solubility, fast drying and wide use. It is a very important organic chemical raw material and an excellent industrial solvent, and is widely used in the production process of acetate fiber, ethyl fiber, chlorinated rubber, vinyl resin, acetate fiber resin, synthetic rubber, paint and paint. Its main uses are: as a Chemicalbook industrial solvent, used in coatings, adhesives, ethyl cellulose, artificial leather, linoleum coloring agent, artificial fiber and other products; As an adhesive, it is used in the production of printing ink and artificial pearls. As an extraction agent, it is used in the production of medicine, organic acids and other products; As a spice raw material, it is used as the main raw material for pineapple, banana, strawberry and other fruit flavors and whiskey, cream and other spices. What we call old wine is good to drink because it contains ethyl acetate. Ethyl acetate has a fruity flavor. Because wine contains a small amount of acetic acid, it reacts with ethanol to form ethyl acetate. Because this is a reversible reaction, it takes a long time to accumulate the ethyl acetate that gives the wine its aroma. In some developed countries, as a non-toxic and pollution-free solvent, it is gradually replacing solvents containing benzene, methyl ethyl ketone and so on, which bring great harm to the human body and the environment. At present, the production routes of ethyl acetate are divided into esterification, acetaldehyde condensation, ethylene addition and ethanol dehydrogenation.
