Reaction Conditions

Reaction Steps

134.1 g (one mole) of L-malic acid and 120 g (1.20 moles) of potassium bicarbonate are dissolved at 60° C. in 200 ml of water. The solution (pH 4.4) is concentrated under reduced pressure to make the total volume thereof about 200 ml. The concentrated solution is cooled to 10° C., and the mixture obtained (i.e., the mixture of the concentrated solution and crystals precipitated) is stirred at the same temperature for 4 hours. After stirring, the mixture had a pH of 6.0. The crystalline precipitates are collected by filtration. 144.6 g of monopotassium L-malate monohydrate are obtained as crystals. Yield: 76%
