A three-step process for the production of acrolein and/or acrylic acid from propylene involves oxidizing the propylene in the presence of a palladium catalyst and acetic acid to produce allyl acetate, hydrolyzing the resulting allyl acetate to produce allyl alcohol and acetic acid, recycling the acetic acid produced to the propylene oxidation step, and oxidizing the allyl alcohol in the presence of a supported palladium-copper or palladium-silver metal catalyst. The acrolein and/or acrylic acid is produced in good yield at low temperatures. Acrylic acid is also produced in good yield at low temperatures by the catalytic oxidation of acrolein in the presence of the supported palladium-copper or palladium-silver metal catalyst. |
