Measurement and Correlation of Solubility of Fructose Diphosphate Sodium in Ethanol + Water Mixtures

Using a laser monitoring observation technique, the solubility of fructose diphosphate sodium in binary solvent of ethanol + water mixtures was experimentally measured in the temperature ranging from 298.15 K to 333.15 K at atmospheric pressure. The solubility of fructose diphosphate sodium increased with an increase of temperature and quality percentage of water. Experimental solubility data were correlated with semi-empirical models; and the calculated solubilities of fructose diphosphate sodium show good agreement with the experimental values.

Solubility of Stearic Acid in Ethanol, 1-Propanol, 2-Propanol, L-Butanol, Acetone, Methylene Chloride, Ethyl Acetate and 95% Ethanol from (293 to 315) K

Solubility of stearic acid in ethanol, 1-propanol, 2-propanol,l-butanol, acetone, methylene chloride, ethyl acetate and 95% ethanol was experimentally determined by the synthetic method from (293 to 315)K. The laser monitoring observation technique was used to determine the disappearance of the solid phase in a solid + liquid mixture. The solubility of stearic acid in methylene chloride was found to be the highest, and the value in 95% ethanol was the lowest. Results are correlated by semi-empirical equations, which show a good fit to the experimental data.
