ABSTRACT
The condensation of formaldehyde and acetic acid to acrylic acid (AA) is considered as one of the important routes for the clean and high value utilization of coal-based methanol derivatives. Herein, we successfully synthesized environment-friendly NASICON catalysts using Ti(SO4)2 as the titanium source. With guaranteed high selectivity (â¼78%), the space time yield of AA + MA (methyl acrylate) can be up to 123.9 µmol g-1 min-1, far higher than the results reported previously. Based on the characterizations, it is demonstrated that the modulation of the acidic and basic properties (including distribution, ratio of B/L, etc.) led by the specific elemental and hybrid TiP2O7 phase plays crucial roles in catalyst supremacy.
