| Abstract: | Latest progress in the research on the catalysts for aldol condensation of propionic acid or propionic ester to methacrylic acid (MA) or methyl mathacrylate are reviewd, including influence of different carriers, supported metal canons and reaction conditions on catalytic activity and selectivity. The processes for decoking of the catalysts are also outlined. It is pointed out that vapor-phase condensation on metaldoped Cs/SiO2 is the main trend in this field. |
