DL-Malic acid Usage And Synthesis
DescriptionWhite 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 Propertieswhite crystalline powder
UsesDL-malic acid is primarily used in the food and beverage industry.
DefinitionChEBI: Malic acid is a 2-hydroxydicarboxylic acid that is succinic acid in which one of the hydrogens attached to a carbon is replaced by a hydroxy group. It has a role as a food acidity regulator and a fundamental metabolite. It is a 2-hydroxydicarboxylic acid and a C4-dicarboxylic acid. It is functionally related to a succinic acid. It is a conjugate acid of a malate(2-) and a malate.
Flammability and ExplosibilityNonflammable
Purification MethodsCrystallise 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.]
