General description

Ethyl acetate, a carboxylate ester, is bio-friendly organic solvent with wide range of industrial applications.[56] Its synthesis by reactive distillation[57][58] and by acceptorless dehydrogenative dimerization of ethanol has been explored.[82] Its utility as a less toxic alternative to diethyl ether in the formalin-ether (F-E) sedimentation procedure for intestinal parasites has been investigated.[21] Its ability as an acyl acceptor in the immobilized lipase-mediated preparation of biodiesel from crude vegetable oils has been examined.[22] The complete degradation of ethyl acetate to CO2 using manganese octahedral molecular sieve (OMS-2) has been investigated.[62]

Application

Ethyl acetate may be used in the following processes:
  • Preparation of thin films of TiO2 (titanium dioxide) on glass.
[63]
  • As an extraction medium in the multi-residue analysis of pesticide residues in fruit and vegetables.
  • [09]
  • Acetylation of primary amines to form amides in the presence of dimethyltin(IV) acetic acid distannoxane.
  • [65]
    Meets urethane grade requirements (H2O ≤ 0.05%)
