The solubility data of amprolium hydrochloride in 12 pure solvents including methanol, ethanol, n-propanol, isopropanol, n-butanol, i-butanol, n-octanol, acetone, ethyl 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 minimum 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 > ethyl acetate > n-butanol > isopropanol > i-butanol > acetonitrile > n-octanol. Moreover, the results of infrared 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), respectively. 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.

273.15–313.15 K温度范围内盐酸氨丙铵在纯溶剂中的溶解度和模型相关性

测定了盐酸安普鲁铵在12种纯溶剂中的溶解度数据,包括甲醇,乙醇,正丙醇,异丙醇,丁醇,丁醇,辛醇,丙酮,乙酸乙酯,1,4-二恶烷,乙腈和环己酮在T = 273.15至313.15 K的温度范围内。在甲醇中获得最大值(在T = 313.15 K时x = 12.99×10 –4,以摩尔分数计),而在辛醇中获得的最小值(x = 2.0×10 -6Ť= 273.15 K,以摩尔分数计)。正如预期的那样,所有选定溶剂中的温度都随着温度的升高而增加。从高到低的值遵循以下顺序:甲醇>丙酮>环己酮>乙醇> 1,4-二恶烷>正丙醇>乙酸乙酯>丁醇>异丙醇>丁醇>乙腈>辛醇。此外,红外光谱图的结果表明在测定过程中没有多晶型物的转化或溶剂化物的形成。修改后的Apelblat方程和λ ħ方程式被应用到的溶解度数据相关联。均方根偏差(RMSD)和相对平均偏差(RAD)的最大值为4.02×10 –5(在甲醇中)和4.77%(在乙醇中)。此外,在改性Apelblat方程选择的两个统计值比λ在显著较小ħ方程。因此,修改后的Apelblat方程更适合于关联溶质在所选溶剂中的溶解度。更重要的是,在重结晶之前,溶解度数据对工程师和研究人员而言将是重要的。
