General description

Ethyl acetate (EA), a carboxylate ester, is bio-friendly organic solvent with a wide range of industrial applications. Its synthesis by reactive distillation and by acceptorless dehydrogenative dimerization of ethanol has been explored. Its ability as an acyl acceptor in the immobilized lipase-mediated preparation of biodiesel from crude vegetable oils has been examined. The complete degradation of ethyl acetate to CO2 using manganese octahedral molecular sieve (OMS-2) has been investigated. EA is an effective alternate solvent of diethyl ether, employed for the concentration of eggs, larvae, and cysts in fecal specimens during the Formalin-ether sedimentation technique. Acetaldehyde is reaction intermediate formed during the oxidative combustion of ethanol and ethyl acetate in the presence of copper oxide embedded on Ce-doped titania surface.

Application

Ethyl acetate may be used in the following studies:
  • As solvent for the isolation of Rose hip (Rosa canina L., Rosaceae) powder, via sonication.
  • As solvent for the abstraction of volatile thiols from wine for their quantitative estimation by gas chromatography/mass spectrometry (GC-MS).
  • Preparation of thin films of TiO2 (titanium dioxide) on glass.
  • As an extraction medium in the multi-residue analysis of pesticide residues in fruit and vegetables.
  • Acetylation of primary amines to form amides in the presence of dimethyltin(IV) acetic acid distannoxane.
