Abstract

Isbu bulus bir katalizör tasiyiciya suda eriyebilir paladyum ve altin bilesimleri emdirildigi ve bunu takiben sabitlestirildigi ve sabitlestirilmis altin ve paladyum bilesimlerinin paladyum ve metal altina indirgendigi daha sonra da tasiyiciya bir kez daha ikinci bir miktarda suda eriyebilir altin bilesimi emdirildigi bir katalizör hazirlama yöntemi ile ilgilidir. Ikinci altin bilesimi miktari sabitlenir ve daha sonra metal altina indirgenir. Daha sonra katalizöre potasyum asetat gibi bir alkali metal asetat emdirilir. Katalizör vinil asetat gibi doymamis esterleri sentezlemek üzere kullanilabilir.
