Measurement on excess thermodynamic functions of binary mixtures of 1-heptanol and 3-amino1- propanol

In recent years, measurements of thermodynamic, and transport properties have been adequately employed in understanding the nature of molecular systems and physico-chemical behavior in liquid mixtures [1]. When two liquids are mixed together, the resulting changes in physical and thermodynamic properties can be considered as a sum of several contributions due to free volume change. Excess thermodynamic properties of mixtures are useful in the study of molecular interactions and arrangements. Thermodynamic properties derived from the measurement of density and viscosity for binary mixtures is useful in understanding the nature and type of intermolecular interactions between the component molecules. The liquids used in the present study are important due to their various industrial applications. The amines are commonly used in oil refineries, in petroleum chemical plants, in ammonia factories, and on natural-gas rigs [2-4].
