As far as possible and customary, SI units are used. Unless otherwise noted, the data given apply to standard conditions .

Lead (IV) acetate forms colorless, prismatic monoclinic crystals that smell of vinegar in moist air . It is the lead salt of the + IV oxidation state of acetic acid with the constitutional formula Pb (CH ₃ COO) ₄ . It is a strong oxidizing agent . The compound is readily soluble in hot glacial acetic acid. In water, hydrolysis takes place in lead dioxide and acetic acid.

Extraction and presentation

Lead (IV) acetate is normally produced by reacting lead (II, IV) oxide (“red lead”) with hot glacial acetic acid or a mixture of glacial acetic acid and acetic anhydride .

use

Lead (IV) acetate is found in organic chemistry and the like. a. Use as an oxidizing agent for Criegee's glycol cleavage or as a dehydrating and hydroxylating agent .
