Studies on acoustical parameters, thermodynamical properties and theoretical evaluation of morpholine with ortho xylene in isopropanol at 303K, 308K and 313K using ultrasonic sound

Abstract

Ultrasonic velocity (U), density (ρ) and viscosity (η) have been measured for morpholine with ortho-xylene in isopropanol at 303K, 308K & 313K. From these experimental values, the adiabatic compressibility (β), acoustic impedance (Z), free length (Lf), free volume (Vf), internal pressure (πi), cohesive energy (CE), Lenard Jones Potential (LJP) and viscous relaxation time (r) have been calculated and their importance are discussed. Formation constant (K) values of the compounds have been determined by using a modified Bhat equation. The thermodynamical parameters have also been computed and the complexes are thermodynamically stable as noticed from their free energy of formation values. The theoretical values of ultrasonic velocity have been calculated at respective temperatures using the Nomoto’s relation (UNOM), Impedance relation (UIMP), Ideal mixing relation (UIMR) and Junjie’s relation (UJUN) and these values are further confirmed by Chi-Square test analysis. The molecular interaction parameter has been calculated by using the experimental and theoretical ultrasonic velocity values.
