Potassium perrhenate Usage And Synthesis

Chemical Properties

white to slightly beige powder

Uses

The reduction of KReO4 in the preparation of cyclopentadienyltricarbonylrhenium complexes has potential as a model for the syntheses of technetium and rhenium organometallic radiopharmaceuticals.1

Uses

A powerful oxidizer. Also used for spectrometry, tungsten wire cathode coating color film and as catalyst. Potassium perrhenate is used as strong oxidizing agent and used in the synthesis of technetium and rhenium organometallic radiopharmaceuticals.

Uses

The reduction of KReO4 in the preparation of cyclopentadienyltricarbonylrhenium complexes has potential as a model for the syntheses of technetium and rhenium organometallic radiopharmaceuticals.

Purification Methods

It is crystallised from water (7mL/g), then fused in a platinum crucible in air at 750o.
