Abstract
Postupak za pripremanje katalizatora po kome je nosač katalizatora impregnisan jedinjenjima paladijuma i zlata rastvorljivim u vodi, koja su potom fiksirana a zatim su fiksirana jedinjenja paladijuma i zlata redukovana u metalni paladijum i zlato, posle čega je nosač impregnisan drugom količinom jedinjenja zlata rastvorljivog u vodi. Druga količina jedinjenja zlata je fiksirana a onda redukovana u metalno zlato. Katalizator se potom impregniše acetatom nekog alkalnog metala kao što je kalijum acetat. Katalizator se može koristiti za sintezu nezasićenih estara kao što je vinil acetat.
