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.

By application, the global ethyl acetate market is segmented into food and beverage, pharmaceutical, cosmetics, textiles, paints and coatings, adhesives and sealants, and others.
The anti-inflammatory activity of the methanol extracts and n-hexane, chloroform, ethyl acetate, and water fractions of Lathyrus species was investigated using HRBC membrane stabilization.
Crude ethyl acetate extract was checked for its antibacterial and antifungal activity against B.
(ZnS[O.sub.4], Ca[Cl.sub.2], MgS[O.sub.4], Co[Cl.sub.2], KCl and EDTA) in three different concentrations 50,100 and 200 (ppm) were added to the ethyl acetate extracts of E.
After 48 h of treatment, the mortality of HCT-116 cell was shown by treatment of extract, n-hexane and ethyl acetate fraction, but didn't show inhibition activity from ethanolic fraction (Table II).
The extract, ethyl acetate fraction, and water fraction have antibacterial activity against PAMR is shown by the inhibition zone or clear zone.
The ethyl acetate extract induced 82%, 58%, and 62% suppression, the methanol extract induced 68%, 34%, and 27%, and the aqueous extract 72%, 44%, and 24% suppression for the doses of 500, 250, and 100 mg/kg, respectively.
A portion of the crude extract was then suspended in water (500 mL) and successively extracted with petroleum ether (3 x 500 mL), ethyl acetate (3 x 500 mL), and n-butanol (3 x 500 mL).
The results show that some or all of the components of the ethyl acetate fraction have significant strong DPPH radical-scavenging activities in vitro.
This research exclusively deals with another scope of analysis using three more solvents: hexane, ethyl acetate and dichloromethane.
