Abstract
Postupak za pripremanje katalizatora sa impregnisanim spoljnim slojem nosača, za upotrebu kod proizvodnje vinil acetata od etilena, sirćetne kiseline i nekog gasa koji sadrži kiseonik, pri čemu taj katalizator sadrži paladijum i eventualno zlato nataložene na nosaču katalizatora, naznačen time, što postupak obuhvata stupnjeve po sledećem redosledu: (1) natapanje nosača katalizatora vodenim rastvorom jedinjenja paladijuma i eventualno zlata rastvorljivih u vodi, (2) dovodjenje natopljenog nosača iz stupnja (1) u dodir sa rastvorom neke barijumove soli koja može da reaguje sa jedinjenjima paladijuma i eventualno zlata rastvorljivim u vodi, da bi se na nosač istaložila u vodi nerastvorljiva jedinjenja paladijuma i eventualno zlata, (3) pretvaranje nataloženih, u vodi nerastvorljivih, jedinjenja paladijuma i eventualno zlata, obrazovanih u stupnju (2) u metalni paladijum i eventualno zlato obradom nekim sredstvom za redukovanje, (4) ispiranje proizvoda iz stupnja (3) vodom i (5) dovodjenje proizvoda iz stupnja (4) u dodir sa nekim promotorom i eventualno nekim aditivom na bazi soli barijuma i sušenje katalizatora.
