Reaction Conditions

Reaction Steps

46.2 g (0.334 mole) of potassium carbonate are dissolved in 500 ml of an aqueous L-malic acid solution[L-malic acid content: 75.9 g (0.566 mole)/500 ml]. The solution (pH 4.4) is concentrated at 60° C. under reduced pressure to make the total weight thereof about 170 g. 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 2 hours. After stirring, the mixture had a pH of 5.8. The crystalline precipitates are collected by filtration. 80.9 g of monopotassium potassium L-malate are obtained.
