Lead Benzoate is a white crystalline powder that loses its water of hydration when heated to 100 °C. It is slightly soluble in cold water (0.16 g/ 100 mL at 20 °C) and somewhat more soluble in warm water (0.31 g/100 mL at 49.5 °C).
Lead benzoate monohydrate [CAS: 6080-57-5], Pb(C6H5CO2)2 · H2O, mol wt 467.43, is a white crystalline powder that loses its water of hydration when heated to 100 °C. It is slightly soluble in cold water (0.16 g/ 100 mL at 20 °C) and somewhat more soluble in warm water (0.31 g/100 mL at 49.5 °C).
Lead benzoate is used as an antioxidant in organolead engine lubricants, as a catalyst in a blowing agent for polyethylene foams, and in fluorescence quenching of organic phosphors.
The salt may be prepared by adding benzoic acid to a slurry of litharge, PbO, or by the reaction between solutions of sodium benzoate and a soluble lead compound.
