Gu, Jianhong published the artcileSolubility and Model Correlation of Amprolium Hydrochloride in Pure Solvent at the Temperature Range of 273.15-313.15 K, Safety of n-Octanol, the main research area is solubility model correlation amprolium hydrochloride pure solvent.
The solubility data of amprolium hydrochloride in 12 pure solvents including methanol, ethanol, n-propanol, isopropanol, n-butanol, i-butanol, n-octanol, acetone, Et acetate, 1,4-dioxane, acetonitrile, and cyclohexanone was determined at temperature range from T = 273.15 to 313.15 K. The maximum value was obtained in methanol (x = 12.99 × 10-4 at T = 313.15 K, in mole fraction) and the min. data in n-octanol (x = 2.0 × 10-6 at T = 273.15 K, in mole fraction). As expected, it increased with rising temperature in all of the selected solvents. The values from high to low obeyed the following sequence: methanol > acetone > cyclohexanone > ethanol > 1,4-dioxane > n-propanol > Et acetate > n-butanol > isopropanol > i-butanol > acetonitrile > n-octanol. Moreover, the results of IR spectrogram indicated that there was no polymorph transformation or solvate formation during the determination process. The modified Apelblat equation and λh equation were applied to correlate the solubility data. The maximum values of the root mean square deviation (RMSD) and relative average deviation (RAD) were 4.02 × 10-5 (in methanol) and 4.77% (in ethanol), resp. Moreover, two statistical values selected in modified Apelblat equation are significantly smaller than those in λh equation. Therefore, modified Apelblat equation is more suitable to correlate the solute solubility in selected solvents. More importantly, the solubility data will be significant to the engineers and researchers before recrystallization
