Mercury(II) stearate is a metal-organic compound, a salt of mercury and stearic acid with the chemical formula C36H70HgO4.[2] The compound is classified as a metallic soap, i.e. a metal derivative of a fatty acid. The compound is highly toxic by inhalation, ingestion, and skin absorption.[1]
Synthesis
An exchange reaction of sodium stearate and mercury dichloride:
- [math]\displaystyle{ \mathsf{ HgCl_2 + 2C_{17}H_{35}COONa \ \xrightarrow{}\ Hg(C_{17}H_{35}COO)_2\downarrow + 2 NaCl } }[/math]
Also, heating mercurious oxide with stearic acid.[3]
Physical properties
The compound forms yellow waxy substance.[4]
Uses
It is used as a germicide[1] and as a plasticizer in the production of ceramics.[citation needed]
