A Study of Heteropoly Complexes of Rare Earths as Catalyst Promoter in the Synthesis of Ethyl Acetate

Department of Chemistry, Northwest University and Shaanxi Key Laboratory of Physico-inorganic Chemistry, Xi'an 710069

Received Date: 28 July 2003

The capability of the synthesized heteropoly complexes of rare earths {K₁₀[(O₃₉W₁₁Si) Ln(Gly)₃Ln(SiW₁₁O₃₉)]·9H₂O (Ln=La, Pr, Nd, Sm, Eu, Gd, Tb, Dy)} as the catalyst promoter in the synthesis of the ethyl acetate was studied. The results showed that the quantity of H₂SO₄ used for synthesizing the ethyl acetate can be reduced by 75% and the yield reached 98% at the optional condition.
