Description

General description

Ethyl acetate, a carboxylate ester, is bio-friendly organic solvent with wide range of industrial applications.[1] Its synthesis by reactive distillation[2][3] and by acceptorless dehydrogenative dimerization of ethanol has been explored.[4] Its utility as a less toxic alternative to diethyl ether in the formalin-ether (F-E) sedimentation procedure for intestinal parasites has been investigated.[5] Its ability as an acyl acceptor in the immobilized lipase-mediated preparation of biodiesel from crude vegetable oils has been examined.[6] The complete degradation of ethyl acetate to CO₂ using manganese octahedral molecular sieve (OMS-2) has been investigated.[7]

Application

Ethyl acetate may be used in the following processes:

• Preparation of thin films of TiO₂ (titanium dioxide) on glass.[8]
• As an extraction medium in the multi-residue analysis of pesticide residues in fruit and vegetables.[9]
• Acetylation of primary amines to form amides in the presence of dimethyltin(IV) acetic acid distannoxane.[10]

Meets urethane grade requirements (H2O ≤ 0.05%)
