Ethyl acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH 3 CO 2 CH 2 CH 3, simplified to C 4 H 8 O 2.This flammable, colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, and the decaffeination process of tea and coffee.
An acetate is a salt formed by the combination of acetic acid with a base (e.g. alkaline, earthy, metallic, nonmetallic or radical base). "Acetate" also describes the conjugate base or ion (specifically, the negatively charged ion called an anion) typically found in aqueous solution and written with the chemical formula C 2 H 3 O − 2.
Uranyl acetate is the acetate salt of uranium oxide, a toxic yellow-green powder useful in certain laboratory tests. Structurally, it is a coordination polymer with formula UO 2 (CH 3 CO 2 ) 2 (H 2 O)·H 2 O.
The esters include ethyl acetate, n-butyl acetate, isobutyl acetate, and propyl acetate. They are typically produced by catalyzed reaction from acetic acid and the corresponding alcohol: CH 3 COO−H + HO−R → CH 3 COO−R + H 2 O, R = general alkyl group. For example, acetic acid and ethanol gives ethyl acetate and water.
Ethyl acetoacetate is subject to keto-enol tautomerism.In the neat liquid at 33 °C, the enol consists of 15% of the total. [5]The enol is moderately acidic. Thus ethyl acetoacetate behaves similarly to acetylacetone: [6]
Potassium acetate (as a substitute for calcium chloride or magnesium chloride) can be used as a deicer to remove ice or prevent its formation. It offers the advantage of being less aggressive on soils and much less corrosive: [5] for this reason, it is preferred for airport runways although it is more expensive.
Isopropyl acetate is a solvent with a wide variety of manufacturing uses that is miscible with most other organic solvents, and slightly soluble in water (although less so than ethyl acetate). It is used as a solvent for cellulose, plastics, oil and fats. It is a component of some printing inks [4] and perfumes.
A supersaturated solution of sodium acetate in water is supplied with a device to initiate crystallization, a process that releases substantial heat. Solubility from CRC Handbook. Sodium acetate trihydrate crystals melt at 58–58.4 °C (136.4–137.1 °F), [12] [13] and the liquid sodium acetate dissolves in the released water of crystallization.
