A new polyoxometalates based compound was synthesized by H3PMo12O40 and organic N-donor ligand, which was structurally characterized and studied about catalytic synthesis of Aspirin.The com-pound was synthesized by hydrothermal synthesis, and characterized by the X-ray single crystal diffraction, ele-ment analysis and IR;The reaction activity of catalytic synthesis of Aspirin was studied by double wavelength UV method.Structural analysis shows that the compound belongs to thombohedral lattice system, P -31m space group, and its stable structure successfully prevented the loss of POM.The optimal process for the catalytic syn-thesis of Aspirin is that the reaction temperature is 85 °C and the reaction time is 25min.A new polyoxometalates based compound,[K10tz6][HPMo12O40]· 4H2O, was successfully obtained, which is a kind of green and effi-cient catalyst for the synthesis of aspirin.
