Silver stearate is a metal-organic compound with the chemical formula C
18H
36AgO
2. The compound is classified as a metallic soap, i.e. a metal derivative of a fatty acid (stearic acid).[1][2][3]
Synthesis[edit]
Silver stearate can be obtained by the reaction of sodium stearate and silver nitrate.
Also by the reaction of stearic acid and silver nitrate in presence of DBU.[4]
Physical properties[edit]
Silver stearate forms white powder.[5]
Silver stearate crystals are of triclinic crystal system; cell parameters a = 0.5431 nm, b = 4.871 nm, c = 0.4120 nm, α = 90.53°, β = 122.80°, γ = 90.12°, Z = 2.
The compound is insoluble in water, ethanol, diethyl ether.
