Synthese

A small nickel or platinum boat containing VF 4 is placed in a nickel tube and gradually heated to 650°C in a stream of dry N2 . The exit gases are collected in a large-diameter quartz trap maintained at —78°C. The trap is attached to a drying tube with anhydrous KF to exclude atmospheric moisture. The heating process must be effected slowly, since otherwise the unreacted VF4 is blown out of the reaction tube. The product is allowed to cool in a nitrogen stream and the VF5 is discharged directly from the gas trap into a storage container. A greenish-yellowish residue (VF4) remains in the boat. The yield is almost quantitative.
