Ultrasonic, optical and IR studies of binary mixtures of morpholine with some aromatic hydrocarbons at T = (303.15, 308.15 and 313.15) K

摘要: Abstract In this paper, the speed of sound, ( U ), and refractive index n D ) four binary systems (morpholine + aromatic hydrocarbons) are measured along whole composition range, at 303.15, 308.15 313.15 K normal pressure. Furthermore, FT-IR measurements these mixtures carried out 298.15 K to study complex formation between morpholine aromatic hydrocarbons. From experimental data, deviation in (Δ isentropic compressibility, K S excess E acoustic impedance, Z calculated satisfactorily fitted using Redlich-Kister polynomial equation. These values reported as a function mole fraction, X 1 or volume fraction ϕ morpholine. Moreover, theoretical sound average deviations is well established equations like Nomoto (NMT), Ideal Mixing Rule (IMR) Jacobson's Free Length Theory (FLT). A comparative nine mixing rules studies namely Arago-biot, Dale-Gladstone, Lorentz-Lorentz, Eykman, Weiner, Heller, Newton, Oster Eyring-John has been investigate their validity for over entire three temperatures. Comparison presented terms deviation. The results show that maximum interactions observed morpholine + benzene binaries, supported by data.
