Usage And Synthesis
Chemical Properties

The product is white crystal or crystalline powder, slightly sour in taste. Soluble in boiling water, slightly soluble in water at 25ºC(0.5%), freely soluble in dilute acid and sodium hydroxidde solution and insoluble in ethanol and ethyl etherr. It decomposes when heated to 270 ºC. Its isoelectric point is 2.77 and its specific rotation is associated with the soluble solvent. It is dextral in the acid solution and water solution, but levorotary in the alkali solution. [α]25D+5.05 (C=0.5-2.0 g/ml, H2O). Combined with HNO2, alcohol or acyl chloride, it can produce L- malic acid, ester and amide respectively. It is the ingredient of unripe sugarcane and beet molasses.
