Participants

Reaction Conditions

Reaction Steps

26.8 g (0.2 mole) of L-malic acid and 13.8 g (0.1 mole) of potassium carbonate are dissolved in 200 ml of water. The solution (pH 4.1) is concentrated under reduced pressure to make the total weight thereof 60 g. The concentrated solution is cooled to 10° C., and the mixture (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 5.1. The crystalline precipitates are collected by filtration, washed with an aqueous 80% methanol solution, and dried at 35° C. in air for 16 hours. 23.4 g of monopotassium L-malate are obtained as crystals.
