| 摘要 | The salts of para2tungstic and para2molybdic were heterogenized for their effective use as solid catalysts in the transesterification reaction of dimethyl carbonate and phenol by inserting them between the layers of Mg2Al-hydrotalcite. These catalysts were characterized by FT-IR spectra and X-ray powder diffraction. Polyoxometalates (POMs) clusters were intercalated into the interlayer of layered double hydroxide (LDH) via anion exchange with organic acid precursor in Mg2Al-LDH, and the integrity of the clusters [W7O24]6 – and [Mo7O24]6 - was maintained. The intercalated para-molybdic cluster showed high catalytic activity and reusability in the transesterification under mild reaction conditions. When the reaction was carried out at 180 ℃, with a molar ratio of phenol to DMC of 1∶1 , a reaction time 10 h , and a catalyst amount 1%(wt) , the conversion of phenol was 1010 % , the selectivities of diphenyl carbonate and methyl phenyl carbonate were 1017 % and 8611 % , respectively. |
