Beschreibung

Allgemeine Beschreibung

Potassium nitrate (KNO₃) is a water-soluble inorganic salt that is commonly used as a source of nitrate ions. It is also used as a cocatalyst in various organic transformations.

Anwendung

Potassium nitrate can be used in the following:      

• KNO₃/Al₂O₃ is used as a base heterogeneous catalyst in the production of biodiesel via transesterification reaction. 
• KNO₃/Br₂ catalytic system is used for the aerobic oxidations of sulfides and alcohols.
