Abstract
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.
Claims8
A vapor phase process which comprises oxidizing allyl alcohol by reacting the allyl alcohol with an oxygen containing gas in the presence of a supported two-metal catalyst at a temperature of 125.degree.-320.degree. C., wherein one metal is palladium and the second metal is copper or silver, and recovering a gaseous reaction product mixture containing acrolein and acrylic acid.
