Description

General description

Ethyl acetate, 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 utility as a less toxic alternative to diethyl ether in the formalin-ether (F-E) sedimentation procedure for intestinal parasites has been investigated. 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.

Application

Ethyl acetate may be used in the following processes:

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