Solubility of Vitamin C in Water, Ethanol, Propan-1-ol, Water + Ethanol, and Water + Propan-1-ol at (298.15 and 308.15) K
Solubility data of vitamin C are essential to fields such as medicine, food, and biochemistry. Regarding recent publications, for hydrotropism studies, it is shown that the knowledge of the solubility of vitamin C in different solvents is very important. In the present paper, solubility data of vitamin C in water, ethanol, propan-1-ol, water + ethanol, and water + propan-1-ol were measured by a gravimetrical method at (298.15 and 308.15) K at an atmospheric pressure of 0.0920 MPa. The solubility data were correlated against the mass fraction of water. The solubility of vitamin C in water, ethanol, and water + ethanol was high compared to that with propan-1-ol and water + propan-1-ol.
