Ethyl acetate is one of the simplest carboxylate esters.
Ethyl acetate is the flammable, organic ester of ethanol and acetic acid.
Ethyl acetate appears as a clear colorless liquid with a fruity odor.
Ethyl acetate is the acetate ester formed between acetic acid and ethanol.
Ethyl acetate is found in essentially all organisms, from bacteria to yeast, to plants to humans.
Ethyl acetate has an ethereal, sweet or fruity odor with a sweet, grape or cherry taste.
Ethyl acetate is present in confectionery (ethyl acetate is used in artificial fruit essences), perfumes, and fruits.
Ethyl acetate exists in all eukaryotes, ranging from yeast to humans.
Ethyl acetate is a sweet, anise, and balsam tasting compound.
Ethyl acetate is found, on average, in the highest concentration within a few different foods, such as milk (cow), pineapples, and sweet oranges and in a lower concentration in safflowers.
Ethyl acetate has also been detected, but not quantified, in several different foods, such as alcoholic beverages, oxheart cabbages, agaves, chervils, ryes, and peach.
Ethyl acetate is used in artificial fruit essences.
In the field of entomology, ethyl acetate is an effective asphyxiant for use in insect collecting and study.
Ethyl ethanoate is a moderately polar, clear, colorless liquid solvent with a light fruity odor.
Ethyl Acetate, also known as ethyl ethanoate, is a widely used solvent in organic synthesis that is highly miscible with common organic solvents.
Ethyl ethanoate is cost-effective, highly effective and is easily broken in both air and water simultaneously.
Ethyl ethanoate can be mixed with non-polar solvents and is also used for extractions.
Ethyl acetate is an acetate ester, an ethyl ester and a volatile organic compound.
Ethyl acetate was first synthesized from ethanol and acetic acid.
Ethyl acetates reaction was the classic acid-catalyzed Fischer esterification, which dates back to 1895.
Esters are structurally derived from carboxylic acids by replacing the acidic hydrogen by an alkyl or aryl group.
An alternative method is the Tishchenko reaction in which acetaldehyde disproportionates in the presence of base to the alcohol and the acid that then esterify in situ.
Ethyl acetate has a role as a polar aprotic solvent, an EC 126.96.36.199 (pyroglutamyl-peptidase I) inhibitor, a metabolite and a Saccharomyces cerevisiae metabolite.
The compound is commonly used as a solvent, in extractions and column chromatography.
Ethyl acetate, also known as 1-acetoxyethane or acetic ester, belongs to the class of organic compounds known as carboxylic acid esters.
Because Ethyl acetate is not hygroscopic, ethyl acetate also keeps the insect soft enough to allow proper mounting suitable for a collection.
In organic and in natural products chemistry ethyl acetate is often used as a solvent for reactions or extractions.
Ethyl acetate is a potentially toxic compound.
Acetic acid-ethyl ester or ethyl acetate, also known as 1-acetoxyethane or acetic ester, belongs to the class of organic compounds known as carboxylic acid esters.
In perfumes, Ethyl acetate evaporates quickly, leaving only the scent of the perfume on the skin.
Ethyl acetate is found in many fruits such as pineapples, and sweet oranges and in a lower concentration in safflowers.
Ethyl acetate has also been detected, but not quantified in, several different foods, such as oxheart cabbages, agaves, chervils, peaches, cereal crops, radishes, fruit juices, beer, wine, spirits etc.
Ethyl acetate is the most common ester in wine, being the product of acetic acid and ethanol generated during fermentation.
The aroma of ethyl acetate is most intense in younger wines and contributes towards the general perception of 'fruitiness' in wine.
Industrially, Ethyl acetate is used as a solvent in glues, nail polish removers, and in the decaffeination process of tea and coffee.
Ethyl acetate is widely used as an organic solvent because of Ethyl acetates low cost, low toxicity, and agreeable odor.
Ethyl acetate is also used in paints as an activator or hardener and for colour and inks used to mark fruit or vegetables.
Ethyl Acetate is a compound produced by yeast that is quantitatively the major ester found in both beer and wine.
Esters are aromatic compounds formed by the reaction between alcohols and acids.
Esters are widely found in nature and contribute to the aromas of many varieties of fruit.
Over 90 esters can occur in beer, and the ethyl esters predominate.
Because ethyl acetate is such an influential part of beer aromatics—for good or ill—brewers seek to control its levels in their beers.
Many factors, in addition to the yeast strain employed, have been found to influence the concentration of ethyl acetate formed during fermentation.
These include fermentation temperature, where an increase from 50°F to 77°F (10°C–25°C) has been found to increase the concentration of ethyl acetate from 12.5 to 21.5 mg/L.
Ethyl acetate is readily soluble in alcohol, ether, chloroform, fatty oils and essential oils.
Ethyl acetate is soluble in 12 times the amount of water, in which it slowly decomposes under the influence of light and air to alcohol and acetic acid.
Therefore the solution slowly turns acid.
Ethyl acetate is a good solvent for cellulose nitrate, celluloid, oils, chlorinated rubber, colophonium, gum copal, vinyl resins, ect.
Ethyl acetate is considered to be one of the least environmentally harmful of organic solvents.
Ethyl acetate is very effective while it is easily broken down in both air and water.

-Ethyl Acetate has a sweet smell that is used to bring a fruity flavor to candy, baked goods, gum, etc.
-Ethyl acetate is also used to extract tobacco from cigarettes, decaffeinate tea leaves, and decaffeinate coffee.
The process to decaffeinate coffee can take up to ten hours, the green coffee beans are rinsed with an ethyl acetate solution to remove caffeine from them.
Immersing the green coffee beans in water softens the beans and dissolves the caffeine.
-Ethyl Acetate is added to the water and the caffeine binds to the chemical due to the water holding all the caffeine instead of the coffee beans holding the caffeine.
When the water is heated, the ethyl acetate steams off, taking the caffeine with it.
-Ethyl acetate can also be found in wine.
Ethyl acetate is also common ester in wines, helping to give wines a fruity flavor.
-Ethyl acetate is used as an artificial flavor in ice creams and cakes.
-Ethyl Acetate is used to extract not only within the pharmaceutical industry and for industrial purposes but also in the food and beverage industry.
