Infobox references

Manganese stearate is a metal-organic compound, a salt of manganese and stearic acid with the chemical formula C
36H
70MnO
4.[1][2] The compound is classified as a metallic soap, i.e. a metal derivative of a fatty acid.[3]

Synthesis

Manganese stearate is synthesized by the reaction of stearic acid with sodium hydroxide, followed by reacting with manganese chloride.[4]

Also, the reaction of manganese(II) acetate with stearic acid.[5]

Physical properties

The compound forms pale pink powder.[6]

Insoluble in water.[6]

Uses

The compound is used in organic synthesis reactions.[6]

Also as an oxidant additive for oxo-biodegradable polymers (for example, high-density polyethylene).[7]
