General description

Sodium nitrate is a water soluble inorganic salt that is commonly used in fertilizers. Due to its thermal stability at high temperature, it shows potential as a phase change material (PCM) for thermal energy storage.

Application

Sodium nitrate may be used for the modification of natural phosphate for use as a basic catalyst for Claisen-Schmidt condensation. It may also be used in the nitration of benzene in trifluoroacetic acid.

General description

Potassium nitrate is a water-soluble inorganic salt that is commonly used as nitrogen fertilizer. It is also found in toothpastes as a desensitizer for tooth hypersensitivity. The addition of KNO3 to growth medium has shown to promote growth in salt stressed melon plants.

Application

Potassium nitrate may be used in the synthesis of 5-bromo-8-nitroisoquinoline via bromination of isoquinoline using N-bromosuccinimide.
