  • Publication number: 20240327327
    Abstract: A process for producing methacrylic acid comprising: a) producing methacrolein from propionaldehyde and formaldehyde; b) producing methacrylic acid in an oxidative reaction from the methacrolein produced in step a) and water. Step b) is performed at a pressure above 1 bar. Step c) is performed in a reactor system in a liquid phase reaction in the presence of a heterogeneous noble metal-containing catalyst, where the reactor system comprises an oxygen-containing gas. An average concentration of methacrolein in step b) is less than 40 wt % based on the total weight of water and methacrolein. The reactor system of step b) has an average ratio of water to methacrolein less than 40:1 based on an average amount of water and methacrolein entering and exiting the system.

  • Publication number: 20240228417
    Abstract: Acrolein is produced by selectively oxidizing iso-propanol over a first mixed metal oxide catalyst in the presence of oxygen in the vapor phase. The first mixed metal oxide catalyst comprises oxides of molybdenum and bismuth. Acrylic acid is produced by selectively oxidizing the acrolein over a second mixed metal oxide catalyst in the presence of oxygen in the vapor phase. The second mixed metal oxide catalyst has a different composition from the first mixed metal oxide catalyst.
