Manganese stearate is a metal-organic compound, a salt of manganese and stearic acid with the chemical formula (C17H35CO2)2Mn. The compound is classified as a metallic soap, i.e. a metal derivative of a fatty acid.[1] The pure solid is white, but some impure samples appear brownish.[2]
Synthesis and uses
Manganese stearate is synthesized by the reaction of sodium stearate with manganese chloride.[2]
It is a precursor to Mn-doped zinc selenide phosphors.[2]
Also as an oxidant additive for oxo-biodegradable polymers (for example, high-density polyethylene).[3]
