Lactic Acid → Calcium Lactate

Participants

Reaction Steps

Feed grade (80%) lactic acid in the amount of 35 g is divided into three equal fractions. Calcium hydroxide, 10.153 g, and 0.946 g of calcium oxide are combined, mixed, and 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. The reaction heat can be modified by adjusting the ratio of calcium oxide to calcium hydroxide.
