用声学方法研究308.15K时Schiff碱在1,4-二氧杂环已环和二甲基甲酰胺溶液中的性质

摘要

Density,viscosity and ultrasonic velocity of solutions of four Schiff basesin 1,4-dioxane and dimethylformamide(DMF)were measured at308.15K.Various acoustical properties such as specific impedance(Z),adiabatic compressibility(κs),Rao'smolar sound function(Rm),the van der Waals constant(b),molar compressibility(W),intermolecular free length(Lf),relaxation strength(r),solvation number(Sn),were calculated.The results are interpreted in terms of molecular interactions occurring in the solutions.
