Anwendungen

Lead(II) nitrate is employed in industrial applications such as heat stabilization in nylon and polyesters and coatings of photothermographic paper. It is utilized to improve the leaching process in the gold cyanidation. It finds applications as a lead paint as well as a source of dinitrogen tetroxide. As an oxidant, it is used in the oxidation of benzylic halides to aldehydes in organic synthesis. It is also used in the preparation of dithiocarbamates from isothiocyanates. It acts as a scavenger of bromide in nucleophilic substitution reactions.

Bemerkungen

Incompatible with strong reducing agents, organic materials and powdered metals.
