Citric acid monohydrate Usage And Synthesis
Chemical Propertieswhite crystals or powder
Purification MethodsCrystallise it from hot H2O solution (w/w solubility is 54% at 10o, 71% at 50o and 84% at 100o. The monohydrate (softens at ~75o and melts at ~100o) dehydrates in air or when heated gently above 40o . The triethylester ( M 276.3, b 127o/1mm, 294o/atm, d 4 1.137, n D 1.4420.) is a bitter tasting oil. [Beilstein 3 H 556 and 568, 3 IV 1272.]
