Yield:617-48-1 97%
Reaction Conditions:
with sodium;iron
Steps:
1 Example 1
The thus obtained L-malic acid solution contained 0.13% fumaric acid, 1.5 ppm iron, 4.5 ppm sodium, less than 100 ppm chloride and less than 100 ppm sulfate. The solution was treated with 7.5 grams of low iron activated carbon (Eponit 113 Spezial). The mixture was held at 60° C. for 60 minutes with stirring and the filtered at this temperature. The filtrate was evaporated to dryness at 60° C. and 15 mbar. Hereby there were obtained 49.1 grams of L-malic acid, corresponding to a yield of 97%, based on the L-malic acid which was contained in the reaction mixture. The L-malic acid was colorless.
