The aldol condensation of methyl propionate and formaldehyde is perspective process for simultaneous obtaining of this methacrylate monomers. It was found that zirconium-containing catalysts are active in this process. The effect of zirconium content in the catalyst on methyl propionate conversion and yield of methyl methacrylate and methacrylic acid has been determined. The best catalyst for methyl propionate condensation with formaldehyde has been found.enmethyl methacrylatemethacrylic acidaldol condensationmethacrylatescatalystzirconium oxideConference Abstract364-365
