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.
