Thermodynamic Excess Properties and FTIR Spectroscopic Studies of Binary Mixtures Containing Propiophenone and 2- Alkoxy Ethanolsat Temperatures 303.15K, 308.15K, 313.5Kand 318.15K

Abstract

Densities ρ, viscosities η and ultrasonic speeds of soundof binary mixtures of Propiophenone (PPH) with 2-Alkoxy Ethanols [2-Methoxy Ethanol, 2-Ethoxy Ethanol, 2-Butoxy Ethanol] have beenmeasured over the entire composition range from 303.15K to 318.15K and at atmospheric pressure 0.1MPa. Theworked out experimental data has been used to calculate various acoustical parameters like excess molar volume V E , excess ultrasonic velocity U E , acoustic impedance Z, excess acoustic impedance (Z E ), isentropic compressibility KS,excess isentropic compressibility Ks , intermolecular free length Lf,excess intermolecular free-length (Lf ), deviation in viscosity Δη were calculatedand the computed results were fitted with the Redlich Kister equation to estimate the binary coefficients and standard deviation between experimental and calculated data.At different concentrations, FTIR analysis has been done for the above binary mixtures to confirm the hydrogen bonding presence.
