Abstract

Findelt kobberpulver som er eg- net for fremstilling av kobberkataly- sator for metylklorsilansyntesen frem- stilles ved at vandig kobbersaltopp- løsning innføres i en vandig suspensjon av jernpulver. Ved utførelsen av frem- gangsmåten kan spesielt kobbersaltopp- løsning utvunnet fra prosessrester fra metylklorsilansyntesen anvendes.
