설명

일반 설명

Silver nitrate, also known as Nitric acid silver(I) salt, is an odorless, colorless, or white versatile inorganic compound widely used as an oxidant and cauterizing agent due to its sclerosing, dehydrating, and escharotic properties. It is commonly used as a catalyst in the hydrolytic oxidation of organosilanes, leading to the production of high hydrogen yield and organosilanols.

애플리케이션

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.
