Rhenium can be prepared from its most known compound, namely
Potassium perrhenate, KReO4. What makes it complex, is the return
of perrhenate, or perrhenic acid, from Re in the presence of oxygen
and water. Therefore it is better done in a closed system with noble gas
around. However, the process includes dissolution of KReO4 in hot water,
acidification with e.g. HCl and reduction, e.g. with Zinc powder. If you do not mind losing some Re, then, if not in closed system, follow the reduction quickly with elimination of remaining Zn with HCl, rinse several times with water, and,
especially with acetone. This will eliminate all side products (which are soluble in acetone) and leave the Re dry, and more or less clean, technical so to speak,
before quickly packaging it in a closed vial.
