What is Promotional effect of Cs modification to NASICON material on aldol condensation of acetic acid and formaldehyde to acrylic acid about?
The production of high value-added oxygenated chemicals from methanol and its derivatives is one of the important ways of coal conversion and clean and efficient utilization. Herein, a series of environmentally-friendly Cs-modified NASICON materials were applied to catalyze the aldol condensation of acetic acid (HAc) and formaldehyde (FA) to acrylic acid (AA) and methyl acrylate (MA). Encouragingly, the selectivity of target products (AA + MA) was highly up to 92.2%, corresponding to the space–time-yield more than 48.0 μmol·gcat - 1·min- 1 over the 2Cs/NSC catalyst, achieving the synchronization of good selectivity and productivity for the target products. Characterization results demonstrated that the acid-base modulation by Cs was responsible for catalyst supremacy. The weak basic sites on catalyst surface were efficient in adsorbing and activating HAc. Plenty of acidic sites especially the medium-strong and strong acidic sites were more favorable for the AA formation.
