Abstract

Ovaj pronalazak obezbedjuje heterogeni bimetalni paladijumsko-zlatni katalizator za proizvodnju vinil acetata od etilena, sirćetne kiseline i kiseonika. Katalizator prema pronalasku priprema se obrazovanjem prve tanke disperzione prevlake koloidnog paladijuma na površini podloge katalizatora, preko koje se nanosi druga tanka disperziona prevlaka koloidalnog metalnog zlata na površinu podloge katalizatora. Koristi se neko organsko jedinjenje zlata za nanošenje disperzije zlata na površinu podloge katalizatora. Organsko jedinjenje zlata ne zahteva postupak fiksiranja, koji je normalno uzrok malog zadržavanja metalnog zlata. Preporučljiv paladijumsko-zlatni katalizator prema pronalasku obezbedjuje veliko zadržavanje metalnog zlata, i iskazuje trajnost i dugotrajnu selektivnost u proizvodnji vinil acetata.
