合成了一系列新的二氢吡啶衍生物,并通过IR,1 H NMR,13 C NMR和质谱数据表征了所有这些合成的化合物。对于所有这些化合物,通过重量分析法在各种极性和非极性溶剂(例如甲醇,乙醇,1-丙醇,1-丁醇,氯仿,乙酸乙酯和1,4-二恶烷)中测定溶解度。已经发现,溶解度随温度而增加,并且对于所有化合物而言,在1,4-二恶烷中溶解度都更大。修改后的Apelblat和Buchowski- Ksiazczakλh使用模型将实验溶解度与温度相关联。使用Van't Hoff和Gibb方程,还从溶解度数据中评估了一些热力学参数,例如Gibb的自由能,焓和溶解熵。

synthesized, and characterization of these synthesized compounds has been done by IR, 1H NMR, 13C NMR, and mass analyses. The densities (ρ), viscosities (η), and ultrasonic velocities (U) of these dihydropyridine derivatives have been measured in dimethyl sulfoxide at different temperatures over a wide range of molalities. From these experimental data for ρ, η, and U, various acoustical parameters and some

synthesized compounds was done by IR, 1H NMR, 13C NMR and mass spectral data. For all these compounds, solubility was determined by gravimetric method in various polar and non-polar solvents such as methanol, ethanol, 1-propanol, 1-butanol, chloroform, ethyl acetate and 1,4-dioxane. It is found that solubility increases with temperature and is found to be greater in 1,4-dioxane for all the compounds. The
