Experimental values of the density and ultrasonic velocity have been measured for binary mixtures of butylamine with 1-butanol
and with tert-butanol at temperatures of 293.15, 303.15 and 313.15 K over the entire mole fraction range. From these data, the excess molar
volumes, deviations in isentropic compressibility, excess internal pressures, and excess molar enthalpies have been calculated.
All of the excess functions were fitted to Redlich-Kister polynomial relations to estimate the adjustable parameters along
with the standard deviations of the fits. The variations of these excess functions with mole fraction of butylamine have been
examined. The changes in these parameters with composition suggest that the interaction between butylamine and 1-butanol is
strong, whereas its interaction with tert-butanol is weak. Further, the partial molar volumes and partial molar compressibilities at infinite dilution have also been
evaluated since these parameters provide better insight for studying intermolecular interactions. 相似文献

通过2-溴-1-(对甲苯基)乙醛与三(对甲苯基)膦的反应制备α-磷配体:1-(对甲苯基)-2-(三对甲苯基-5-亚磷酰基)乙醛(L)。氯化镉和溴化汞与L分别反应,生成配合物[Cd(L)Cl_2]_2(C1)和[Hg(L)(μ_2-Br)Br]_2(C2)。用IR和NMR(~1H,~(13)C,~(31)P)对配合物进行了表征。通过单晶X射线衍射测定了C2的结构,并在B3LYP/6-31G~*水平对C2的结构进行了DFT计算研究,以揭示C2的复合反应位点与Schiff碱等亲核基团的相互作用。 相似文献
