Description

General description

Potassium nitrate (KNO₃) is a water-soluble inorganic salt that is commonly used as a source of nitrate.

Application

Potassium nitrate can be used in the following:      

• KNO₃/Al₂O₃ is used as a solid base catalyst to synthesize by vapor-phase methylation of catechol with dimethyl carbonate.
• KNO₃/cetyltrimethylammonium bromide (CTAB) catalytic system is used in the oxidation of benzyl halides to aldehydes and ketones in aqueous media.
• In the Cu/CeO₂ catalytic system, KNO₃ can also be utilized as a promoter to enhance the soot oxidation activity and resistance to sulfur poisoning of the catalyst.
