A process for forming methyl methacrylate can comprise: reacting ethylene, carbon monoxide, and hydrogen, in the presence of a first catalyst comprising a metal carbonyl; removing a first reaction product comprising propionaldehyde; reacting the first reaction product with formaldehyde; removing a second reaction product comprising methacrolein; reacting the second reaction product with oxygen and methanol in the presence of a second catalyst to form a third reaction product comprising methyl methacrylate. Another process for forming methyl methacrylate can comprise: reacting ethylene with carbon monoxide to form propionaldehyde; reacting the propionaldehyde with formaldehyde to form methacrolein; and reacting the methacrolein with methanol and oxygen to form the methyl methacrylate.
