설명

애플리케이션

• Perrhenic acid solution (HReO₄) can be used in dehydrations of oximes, amides, and urea.
• HReO₄ can also catalyze azeotropic dehydration of syn- or anti-aldoximes to yield corresponding nitriles.
• In combination with tertiary arsines, it gives a versatile catalytic system for epoxidation of alkenes with hydrogen peroxide.

It is also used to prepare highly conducting and superconducting synthetic metals.
