Abstract In the binary mixtures of 2-ethyl-1-hexanol with various functional groups (benzyl chloride, 3-methyl aniline, 3-methoxy aniline and 2,6-dimethyl cyclohexanone) densities, speeds of sound and viscosities including those of pure liquids were measured over the entire composition range at different temperatures (303.15, 308.15 and 313.15) K and atmospheric pressure 0.1 MPa. Using this experimentally determined data, the excess/deviation parameters (molar volume, isentropic compressibility and deviation in viscosity) partial molar volumes, partial molar isentropic compressibilities of these components at infinite dilution were calculated. The results are discussed in terms of intermolecular forces between different component molecules in the binary mixture are more than the average intermolecular forces existing between the similar molecules of pure components.

1 Introduction The study of thermodynamic properties of binary mixtures contributes to an understanding of the behavior of different liquids and their functional groups. This information is very useful in the design of industrial process and in the development of theories for the liquid state and predictive methods. Excess thermodynamic parameters of different mixtures are useful in the study of molecular interactions and arrangements. The knowledge of physicochemical properties of nonaqueous binary liquid mixtures has relevance in theoretical and applied areas of research, and such results are frequently used in design process (flow, mass transfer or heat transfer calculations) in many chemical and industrial processes [1]. The excess properties derived from
these physical property data reflect the physicochemical behavior of the liquid mixtures with respect to the solution structure and intermolecular interactions between the component molecules of the mixture [2, 3]. Study of hydrogen-bonded systems is essential and helpful as hydrogen bond plays a vital role in chemical, physical and biological process. Organic compounds containing electronegative group can interact with compounds containing active hydrogen through hydrogen bond. This type of hydrogen bond takes part in role in the stability of biologically important molecules. Alkanols are polar and self-associated liquids and the dipolar association of alkanols decreases when they are mixed with polar compounds containing various functional groups due to formation of hydrogen bonds between 2-ethyl1-hexanol and various functional groups in the mixtures
