Application

Silver nitrate can be used as a catalyst:      
  • For the Friedel-Crafts acylation of benzene derivatives to synthesize corresponding ketones.     
  • In the hydrolytic oxidation of organosilanes to produce hydrogen.

It can be used to prepare some supported acid catalysts for various organic transformations. For example:      
  • AgNO3–SiO2 based catalyst is used to dearomatize spirocyclization.      
  • Polyaniline-AgNO3-PTSA (para-toluene sulfonic acid) catalyst is used to synthesize anti-β-amino ketones via the three-component Mannich reaction of aromatic aldehydes, aromatic amines, and cyclohexanone.

AgNO3 is also used as a precursor salt to synthesize silver nanoparticles.

Silica-supported AgNO3 (AgNO3 -SiO2 ) catalyzes the dearomatizing spirocyclization of alkyne-tethered aromatics far more effectively than the analogous unsupported reagent; in many cases, reactions which fail using unsupported AgNO3 proceed effectively with AgNO3 -SiO2 .
