Evaluation of Non–Linearity (B/A) Parameters of Multicomponent Liquid Systems

Sabia Zafar, Dr. R. K. Singh

Abstract :

Non linearity parameter (B/A) for ternary liquid mixtures of (ethanol+N,N-DMF+cyclohexane) at 298.15 K and (n-pentane+n-hexane+benzene) at 308.15 K have been calculated by three different methods viz. Beyers ,Hartmann and Ballou. Non-linearity parameter is related with thermoacoustical quantities like isobaric acoustical parameter (K),isothermal acoustical parameter (K’) ,isochoric acoustical parameter (K’’) and isothermal and adiabatic compressibility ratio (γ) which depend upon thermal expansion coefficient (α), Sharma parameter (S*) and isochoric temperature coefficient of internal pressure (X) .All above parameters were calculated by using density and ultrasonic velocity values of multicomponent liquid mixtures. In ternary liquid mixture (n-pentane+n-hexane+benzene ),the non-linearity parameter (B/A) values obtained by all three methods are very close to each other but in case of (ethanol+N,N-DMF+cyclohexane),the values by Hartmann and Ballou are close whereas by Beyer’s they are different
