Molecular associations of the liquids viz., aminoethanol (AE), chloroethanol (CE) and phenylethanol (PE) with Ethyl Lactate (EL) as common liquid at different temperatures are examined from experimentally measured values speed ultra sound (U), coefficient viscosity (η) density (ρ). The variation U, ρ η discussed in reference to molecular interactions. From experimental data, various thermodynamic excess parameters computed which critical analysis associations. Excess functions molar volume (VmE) isentropic compressibility (∆κs) observed negative while deviations (∆η) positive all cases. partial volumes corresponding properties have been compared volumes. studies showed that EL AE, CE PE follow order: + AE> CE> PE.
