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
一些新的二氢吡啶衍生物,即4-(4-羟基-3-甲氧基苯基)-6-(2-羟基苯基)-2-氧代-1,2-二氢吡啶-3-腈、4-(4-羟基-3) -甲氧基苯基)-6-(4-羟基苯基)-2-氧代-1,2-二氢吡啶-3-甲腈,6-(4-氯苯基)-4-(4-羟基-3-甲氧基苯基)-2-氧代-合成了 1,2-二氢吡啶-3-腈和 4-(4-羟基-3-甲氧基苯基)-2-氧代-6-苯基-1,2-二氢吡啶-3-腈,并对这些合成化合物进行了表征已通过 IR、1H NMR、13C NMR 和质量分析完成。这些二氢吡啶衍生物的密度 (ρ)、粘度 (η) 和超声速度 (U) 已在二甲亚砜中在不同温度下在很宽的摩尔浓度范围内进行测量。根据 ρ、η 和 U 的这些实验数据,计算了各种声学参数和一些表观摩尔参数。获得的结果根据溶质 - 溶剂和溶质 - 溶质相互作用进行解释,给出结构形成或结构的概念......
