## Preparation

It can be prepared by treatment of rhenium heptoxide with base or by ion exchange from the potassium salt.[2]

Sodium perrhenate can be prepared from rhenium metal with hydrogen peroxide in the presence of base.[3]

2 Re + 7 H

2 \+ 2 NaOH → 2 NaReO
4 \+ 8 H

## Reactions

It reacts with sodium in ethanol to give nonahydridorhenate.[2]

Sodium perrhenate has been used as a precursor of rhenium nitrides (such as Re3N, Re2N, Re3N2, ReN2, ReN3, ReN4), which can be used as catalysts for ammonia synthesis and for hydro-denitrogenation.[4]

It can be used to prepare Re2(CO)10.[3]
