Procedure

In a reaction vessel, 145.83 grams of manganese carbonate, 328.92 grams of propionic acid and 25.38 grams of sodium hydroxide, a relative molar ratio of 2:7:1 respectively, was combined and heated to reflux. Water was removed from the vessel during the reaction by means of a fractional distillation column. The reaction went to completion after 10 hours, producing a dark burgundy solution from which about 80 percent of the remaining acid was removed. The product solidified at 130° C. The final product contained 80.7 percent manganese propionate and 19.3 percent sodium propionate.
