Theoretical Based Studies Of Ultrasonic Velocities Of 1,4-Dioxane In Amines At Temperature 308.15K

: Theoretical velocities of binary liquid mixtures of 1,4-dioxane with ethylamine, diethylamine and triethylamine at 7MHz at temperatures 308.15K, have been evaluated as a function of mole concentration. The experimental values are compared with theoretical models of liquid mixtures such as Collision factor theory (CFT), Free length theory (FLT), Nomoto theory (NOM), Ideal mixing relation (IMR), Impedance Relation (IR), Rao’s Specific Velocity Method(R) and Junjie’s relations (JR). Chi-square tests for the goodness of the fit and average percentage errors are applied to investigate the relative applicability of these theories to the present systems. The variation of molecular interaction of thermo-acoustical parameters of the systems studied with the mole fraction of common compound has been discussed in terms of molecular interactions.
