Descrição

Descrição geral

Molybdic acid is the hydrated form of molybdenum trioxide. It is used in the synthesis Froehde reagent.

Aplicação

Molybdic acid can be used:

• In the preparation of silica-supported molybdic acid catalyst for the synthesis of pyrano [2,3-c] chromene derivatives by condensation of aldehydes, malononitrile, and 4-hydroxycoumarin.
• In the synthesis of Froehde reagent for the presumptive identification of alkaloids like opioids.
• As a molybdenum source in the preparation of MoSe₂.

Outras notas

Consists largely of an ammonium molybdate
