| titleOfInvention | Catalyst for synthesizing dimethyl carbonate by ester exchange of cyclic carbonate and methanol, preparation method and application thereof |
| abstract | The invention belongs to the field of heterogeneous catalysis, and discloses a catalyst for producing dimethyl carbonate by ester exchange reaction of cyclic carbonate and methanol, wherein the catalyst is zinc-aluminum-iron oxide Zn x Al y Fe z O-supported metal oxide LO α And KF catalyst, in which Zn x Al y Fe z O and LO α And the mass ratio of KF is 100: 2-15: 1-5, wherein x, y, z and alpha are the number of atoms in the molecular formula. The invention also relates to a preparation method and application of the catalyst. Compared with a homogeneous catalyst, the catalyst has the advantage that the catalyst and a product are easy to separate; compared with other solid base catalysts, the catalyst has stronger alkalinity, can improve the ester exchange reaction efficiency of cyclic carbonate and methanol, and has higher yield of dimethyl carbonate. |
