| DL-Malic acid Usage And Synthesis |
| Description |
White or nearly white, crystalline powder or granules having a strongly acid taste. One g dissolves in 0.8 mL of water and in 1.4 mL of alcohol. Its solutions are optically inactive. It melts at about 130°. |
| Chemical Properties |
white crystalline powder |
| Uses |
DL-malic acid is primarily used in the food and beverage industry. |
| Purification Methods |
Crystallise the acid from acetone, then from acetone/CCl4, or from ethyl acetate by adding pet ether (b 60-70o). Dry it at 35o under 1mm pressure to avoid formation of the anhydride. [Beilstein 3 IV 1124.] |
