Measurement and Correlation for Solubility of L-valine in Water, Ethanol, N,N-Dimethylformamide, Acetone, and Isopropyl alcohol between 293.15 and 343.15 K
The solubilities of l-valine in water, ethanol, N,N-dimethylformamide, acetone, and isopropyl alcohol were experimentally measured by the synthetic method over the temperature range from (293.15 to 343.15) K at atmosphere pressure. The solubilities of l-valine in pure solvents increase with increasing temperature and in the following order: acetone less than N,N-dimethylformamide less than isopropyl alcohol less than ethanol less than water. The solubilities correlated using the modified Apelblat model show good agreement with the experimental data, and the dissolution enthalpy, dissolution entropy, and the molar Gibbs energy were predicted. The experimental solubilities and the modified Apelblat model can be used as essential data and model in the industrial manufacturing process of l-valine.
