Thermodynamic and Acoustic Properties of Binary Mixtures of Diisopropyl ether or oxolane with N, N-dimethylaniline or N, N-diethylaniline at different Temperatures

A. Ayyasamy

Abstract: The thermodynamic, acoustic and transport properties of non-electrolyte liquid-liquid mixtures provide information about type and extent of molecular interactions and can be used for the development of molecular models for describing the behaviour of solutions. We are engaged in systematic investigations of binary mixtures of aromatic amine with ether at different temperatures. We found speeds of sound, isentropic compressibilities, excess molar volumes and various other related properties of binary mixtures of diisopropyl ether (DIPE) or oxolane with aniline, N-methylaniline, N-ethylaniline, o-toluidine and m-toluidine (primary and secondary arylamines) at 303.15, 313.15 and 323.15 K. It was observed that there exist specific interactions through hydrogen bonding and dipole-dipole interactions between primary/secondary arylamine and ether molecules. Our studies to the binary mixtures formed from DIPE or oxolane with N, N-dimethylaniline (DMA) or N, N-diethylaniline (DEA). Speeds of sound at different temperatures in the investigated binary mixtures have also been estimated through Nomoto model (NM), Van Dael model (VM), Ernst model (EM), impedance model (IM), Schaaffs collision factor theory (CFT), Jacobsons free length theory (FLT), and Prigogine-Flory-Patterson-Oswal theory (PFPOT).
