Ethyl Acetate

Product Information

Ethyl Acetate is one kind of Ester Compounds, the chemical formula is C4H8O2, it is a kind of ester with functional group-COOR (double bond between carbon and oxygen), it can occur alcoholysis, ammonia decomposition, ester exchange, reduction and other common reactions of general esters, it is mainly used as a solvent, edible spice, cleaning and degreasing agent.

Chemical Properties of Ethyl Acetate
Ethyl acetate can occur alcoholysis, ammonolysis, ester exchange, reduction and other common reactions of general esters. Self-condensation in the presence of sodium metal to produce 3-hydroxy-2-butanone or ethyl acetoacetate; and Grignard reagent reaction to produce ketone, further reaction to get tertiary alcohol. Ethyl acetate is relatively stable to heat and remains unchanged when heated at 290°C for 8 to 10 hours. It decomposes into ethylene and acetic acid when passing through red-hot iron pipe, into hydrogen, carbon monoxide, carbon dioxide, acetone and ethylene by zinc powder heated to 300~350℃, and into water, ethylene, carbon dioxide and acetone by dehydrated aluminum oxide at 360℃. Ethyl acetate is decomposed by ultraviolet irradiation to produce 55% carbon monoxide, 14% carbon dioxide and 31% hydrogen or methane and other flammable gases. Reaction with ozone produces acetaldehyde and acetic acid. Gaseous hydrogen halides react with ethyl acetate to form ethyl halide and acetic acid. Hydrogen iodide is the most reactive, while hydrogen chloride requires pressure to decompose at room temperature, and is heated to 150°C with phosphorus pentachloride to form chloroethane and acetyl chloride. Ethyl acetate forms various crystalline complexes with metal salts. These complexes are soluble in anhydrous ethanol but insoluble in ethyl acetate and are easily hydrolyzed in water.

Company information

The company's main import and export products include

(1)Rubber Products：When rubber products are molded, after being pressed under high pressure, the cohesion of the elastomer cannot be eliminated, which often produces unstable shrinkage when the product is molded out of the mold (the shrinkage rate of rubber varies depending on the type of rubber), which can only be eased and stabilized after a certain period of time. Therefore, when a rubber product design at the beginning, regardless of the formula or mold, need to be carefully calculated to match, if not, it is easy to produce unstable product size, resulting in low product quality.

(2)Intermediates：The chemical compound synthesized from simpler compounds and usually intended to be used in later syntheses of more complex products.A usually short-lived chemical species formed in a reaction as an intermediate step between the starting material and the final product.
