Ethyl Acetate

 

CH3COOC2H5, a colorless, volatile liquid with a pleasant, fruity odor.

Ethyl acetate has a boiling point of 77.1°C, a melting point of – 82.4°C, and a density of 0.900 g/cm3 at 20°C. Slightly soluble in water, it is readily soluble in such liquids as alcohol, ether, and chloroform. Ethyl acetate is flammable, and its explosive limits in air are 2.2 and 9 percent by volume.

Ethyl acetate is produced industrially by means of the esterification of ethyl alcohol by acetic acid in the presence of sulfuric acid. It is used as a solvent for cellulose nitrates in the manufacture of paints and varnishes (seeCELLULOSE NITRATE LACOUERS) and is also used in the production of photographic film, motionpicture film, and smokeless powders. A mixture of ethyl acetate and alcohol serves as a solvent for cellulose acetate, polyvinyl butyral, and certain other polymers. Ethyl acetate is also used as a component of fruit flavorings for soft drinks, liqueurs, and candies.

The results using different extracting solvents (benzene, ethylacetate, methylene chloride and ethylene chloride) indicated that methylene chloride is the most appropriate solvent for extraction and that can be attributed to its high extraction efficiency.
It was observed that the mixture of ethylacetate and n- hexane can remove more then 75% while methanol can remove only 20% of parathion from the adsorbent surface.
Acetaldehyde may be reduced to ethanol and react further to form ethylacetate. That reaction, together with acetaldehyde permeation through the package material, could explain the decrease of acetaldehyde values after 21 days of storage.
In both cases, the cannabinoids were extracted with ethylacetate: iso-propanol (8.5:1.5 v/v).
pH value of the filtrate was adjusted to 12 with 0.2 M HCl solution, ethylacetate was added to the filtrate in a flask (molar ratio of ethylacetate to Si[O.sub.2] in [H.sub.2]Si[O.sub.3] 9:10) at a constant temperature using magnetic stirring, thereafter [H.sub.2]Si[O.sub.3] sediment was separated from the solution in a centrifuge, washed with deionized water and dried under 105[degrees]C for 2 h.
cardiaca herb was extracted by water, ethylacetate, oil (by maceration) and by oil in RPE.
The dried residue was fractionated by a step elution with 100 mL of 100% ethylacetate, 100% ethanol and 100% methanol.
Specimen pH was adjusted to 10.5 with 6 mol/L HCI, and extracted with n-butyl chloride/ acetonitrile/ ethylacetate (4:1:1 vol/vol).
Petroleum ether extract was best resolved in toluene : ethylacetate (84:16 v/v) as mobile phase (Wagner 2002).
Several extraction solvents were attempted: diethylether, ethylacetate, chloroform, n-hexane, n-pentane, and dichloromethane.
