Document Type and Number:

WIPO Patent Application WO2002083299

Kind Code:

B1

Abstract:

A catalyst for the manufacture of acrylic acid or methacrylic acid by the oxidation of propylene, acrolein, or isobutylene whereby said catalyst is prepared by reducing a palladium salt or palladium metal to palladium with a reducing agent such as propylene in an oxygen-free single or two phase aqueous organic solvent containing as a co-solvent a maximum concentration of a C2-C6 carboxylic acid or C3-C6 ketone.
