Esters are derived from a carboxylic acid and
an alcohol. Esters comprise most naturally occurring fats and oils, which are
fatty acid esters of glycerol. Esters with low molecular weight are commonly
used as fragrances and found in essential oils. Nitrate esters, such as nitroglycerin,
are known for their explosive properties, while polyesters are important plastics.
Acetic acid and ethonol form the Ester Ethyl acetate.
When acids mate, couple and pair with alcohols, they form compounds called Esters and water. It is as if the alcohols lose their OH heads and the acids lose their H hearts. The heads and hearts find each other and form water like tears of happiness.
The headless and heartless bodies left behind pair to form Esters.
Acetic acid and ethonol form the Ester Ethyl acetate.

Ethyl acetate is a colorless liquid with a
characteristic sweet smell (similar to pear drops) and is used in glues, nail
polish removers, decaffeinating tea and coffee, and cigarettes.
Ethyl acetate (systematically, ethyl
ethanoate, commonly abbreviated EtOAc or EA) is the organic
compound with the formula CH3-COO-CH2-CH3,
simplified to C4H8O2. This colorless liquid
has a characteristic sweet smell (similar to pear drops)
and is used in glues,
nail polish removers, decaffeinating
tea and coffee, and cigarettes (see list of additives in cigarettes).
Ethyl acetate is the ester
of ethanol
and acetic
acid; it is manufactured on a large scale for use as a solvent. The
combined annual production in 1985 of Japan, North America, and Europe was
about 400,000 tons.[3]
In 2004, an estimated 1.3M tons were produced worldwide.[4]
Essigsäureethylester, auch Ethylacetat oder Essigester, ist
eine chemische Verbindung aus der Gruppe der Carbonsäureester. Es ist der Ester von Essigsäure und Ethanol. Die farblose Flüssigkeit
ist ein charakteristisch nach Klebstoff riechendes Lösungsmittel, das in der chemischen
Industrie und in Laboratorien oft verwendet wird.
L'acétate d'éthyle (éthanoate d'éthyle) est un liquide, à l'odeur
caractéristique fruitée. C'est un ester
résultant de l'éthanol et de l'acide acétique utilisé principalement comme solvant. On le trouve, à l'état naturel, en
faibles quantités dans le rhum et dans les raisins endommagés par la grêle.
El etanoato de etilo,
también llamado acetato de etilo según la IUPAC, y de otras formas (ver tabla)
es un éster de fórmula CH3-COO-CH2-CH3.
Su nombre antiguo
es éter de vinagre, en alemán Essig-Äther, de donde proviene el
término "esther" o éster.
El acetato de etilo es un líquido
incoloro, característico de los ésteres, no
residual. Es miscible con hidrocarburos, cetonas, alcoholes y éteres y poco
soluble en agua. Se emplea en arte como disolvente universal.
