Lead(II) laurate is a metal-organic compound with the chemical formula Pb(O₂C(CH₂)₁₀CH₃)₂. It is classified as a metallic soap, i.e. a metal derivative of a fatty acid. Like most soaps, it does not dissolve in water. ^{[2] [3]} Lead soaps have been used as stabilizers and plasticizers in PVC. ^[4]

Preparation

Lead soaps are usually prepared by combining lead(II) oxide with molten fatty acid. An idealized equation is:

PbO + RCO₂H → Pb(O₂CR)₂ + H₂O

Lead carboxylates, which would include lead(II) laurate, have complex structures. ^[5]
