Description
Citric acid monohydrate(CAM) is an organic acid. It can be produced by crystallization from mother liquor of citric acid solution at 20-25°C during citric acid synthesis. Its molar enthalpy of solution in water has been reported to be Δ sol H m (298.15K, m = 0.0203molkg -1 ) = (29061±123)Jmol -1. An investigation of its crystal growth kinetics indicates that growth is linearly dependent on size.ApplicationCitric acid monohydrate may be used: To prepare citric acid solution employed in the acetone method of 68 Ga pre-purification and radiolabeling technique. To prepare Tris-citrate buffer employed for the electrophoresis of bacterial enzymes. To improve the release of diltiazem hydrochloride from melt extruded matrix tablets
