Lactic Acid → Calcium Lactate

Feed grade (80%) lactic acid in the amount of 16.56 g is combined with 24.86 g propionic acid and divided into three equal fractions. Calcium hydroxide, 16.81 g, is divided into three equal fractions. The first fraction of lactic acid is added to 20 g of almond shell meal while stirring. Then, the first fraction of the combined base mixture is slowly added while stirring. The temperature of the mixture is observed to increase and water starts evaporating. When the product appeared to be dry, the same procedure was repeated for the remaining fractions, adding the acid while stirring, adding the base while stirring and drying. After the addition of the last fraction of the base, the evaporation of water from the mixture is closely observed. As soon as the rate of evaporation is observed to decrease, the fumaric acid is added while stirring. Because the produced salt is not yet dry, the fumaric acid agglomerates with the salt, yielding a granule comprising an organic salt and a free organic acid.
