Reaction Steps

An aqueous solution of malic acid was prepared by mixing 134.09 g of malic acid with 50 mL of water. An aqueous solution of calcium oxide was also prepared in a separate container by thoroughly mixing 56.08 g of calcium oxide in 50 mL of water. Next, 54.94 g of ferronyl powder was then added to the malic acid solution. The calcium oxide solution was then slowly added to the iron/malic acid solution. The solution was allowed to mix for approximately 2 hours. The resulting solution was then spray dried to produce a powdered dihydroxycalcium ferrous malate (or calciumhydroxy ferroushydroxy malate).
