Procedure

A preparation of manganese propionate is made by combining 114.95 grams of dry manganese carbonate, 300.30 grams of dry acetic acid, and 40.01 grams of sodium hydroxide. The mixture is heated to reflux with constant stirring. Water with some acetic acid is removed by fractional distillation. Heat is increased until the water and about 80 percent of the acetic acid liquid has been removed. Carbon dioxide is released through a vented condenser. The resulting composition of manganese acetate and sodium acetate in residual acetic acid is poured into a flat metal pan and placed in a freezer until cool. After cooling, the solution solidifies into a pink "glass". The "glass" is ground releasing the acetic acid. A white to slightly pink powder is collected containing manganese acetate and sodium acetate.
