一般描述

Ethyl acetate, a carboxylate ester, is bio-friendly organic solvent with 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.

应用

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 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.
Meets urethane grade requirements (H2O ≤ 0.05%)
