Lead Subacetate
Basic lead acetate, also known as subacetate of lead, is the inorganic compound with the formula Pb3(OH)4(O2CCH3)2. A white solid, it is one of several lead acetates. History Goulard's extract is a solution of lead(II) acetate and lead(II) oxide used as an astringent An astringent (sometimes called adstringent) is a chemical that shrinks or constricts body tissues. The word derives from the Latin ''adstringere'', which means "to bind fast". Calamine lotion, witch hazel, and yerba mansa, a Californian pla ... during the 18th, 19th and early 20th centuries. It was named after its introducer, Thomas Goulard. Lead poisoning and the development of more effective astringents caused doctors to abandon its use. Synonymous or very closely related formulations were known as ''liquor plumbi subacetis dilutus'', ''eau de Goulard'', extract of Saturn, vinegar of Saturn, and liquid acetate of lead. The white water ''eau de Saturne'' differed from ''eau de Goulard'' in not containin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead(IV) Acetate
Lead(IV) acetate or lead tetraacetate is an organometallic compound with chemical formula . It is a colorless solid that is soluble in nonpolar, organic solvents, indicating that it is not a salt. It is degraded by moisture and is typically stored with additional acetic acid. The compound is used in organic synthesis. Structure In the solid state the lead(IV) centers are coordinated by four acetate ions, which are bidentate, each coordinating via two oxygen atoms. The lead atom is 8 coordinate and the O atoms form a flattened trigonal dodecahedron. Preparation It is typically prepared by treating of red lead with acetic acid and acetic anhydride (), which absorbs water. The net reaction is shown: :Pb3O4 + 4 Ac2O -> Pb(OAc)4 + 2 Pb(OAc)2 The remaining lead(II) acetate can be partially oxidized to the tetraacetate: :2 Pb(OAc)2 + Cl2 -> Pb(OAc)4 + PbCl2 Reagent in organic chemistry Lead tetraacetate is a strong oxidizing agent, a source of acetyloxy groups and a general reagent ...
