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
[edit]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
[edit]The compound forms pale pink powder.[6]
Insoluble in water.[6]
Uses
[edit]The compound is used in organic synthesis reactions.[6]
Also as an oxidant additive for oxo-biodegradable polymers (for example, high-density polyethylene).[7]
