<p>A catalytic compsn. for the synthesis of vinyl acetate pour acetic acid and ethylene in a medium free from halogen ions, consists of a combination of a cupric salt, pref. the acetate, and a Pd chelate in which the chelating agent is an amino acid or a peptide. The ratio of Cu to Pd is pref. 1/10 - 10,000, esp. 2-300. Compsn. pref. also includes an alkali metal salt, pref. the acetate. The process may be carried out continuously. Freedom from halogen ions minimises corrosion.</p> |
