Reaction of Methyl Propionate with Methylal over V-Si-P Ternary Oxide Catalysts

Article abstract of DOI:10.1246/bcsj.63.3722

The vapor-phase aldol condensation of methyl propionate with formaldehyde was performed using methylal as the source of formaldehyde.The main products were methyl methacrylate and methacrylic acid.The one-pass yield of methyl methacrylate plus methacrylic acid on methylal basis reached 53 molpercent at a methyl propionate/methylal molar ratio of 2 over the V-Si-P oxide with an atomic ratio of 1:16:3.2.
