Bismuth (III) nitrate is an inorganic chemical compound of bismuth from the group of nitrates .

Extraction and presentation

Bismuth (III) nitrate can be obtained by dissolving bismuth or bismuth (III) oxide in nitric acid. This creates the pentahydrate.

properties

Bismuth (III) nitrate pentahydrate is a colorless solid in the form of rod-shaped, triclinic crystals. When heated from around 60 ° C, it transforms into various basic bismuth (III) nitrates and at higher temperatures into bismuth (III) oxide. It is soluble in strong inorganic acids as well as in glycerine and glacial acetic acid . In water, hydrolysis takes place to form basic salts such as bismuth (III) subnitrate . It forms double salts with metal nitrates .

use

Bismuth (III) nitrate is an excellent oxidizing agent for a large number of 4-substituted Hantzsch- 1,4-dihydropyridines . It is a convenient reagent for the selective oxidation of sulfides to sulfoxides . It is also used as a catalyst for a high-yield Michael addition of various substrates, including amines, imidazoles, and indoles to form enones .
