As biotechnology sweeps the world, researchers are reporting data describing how chemical thermodynamics can be utilized to processes for new biochemical products. It is the integrative coarse- grained feature of thermodynamics that makes it attractive for describing some of the overall features of biological systems. Further, thermodynamic studies of chemical and biological systems are of vital importance particularly from the point of view of contemporarily development of science and technology right from nano- size to macro-molecular levels. The present day advancement in scientific and technological fields is pouring in a huge quantity of new and challenging data that need to be analyzed using thermodynamic tools to understand various aspects of the observed behaviour. In chemical process industries materials are normally handled in liquid form and as a result, the physical, chemical and thermodynamic properties of liquids and their mixtures assume …show more content…
are widely used in chemical industries for the right design of various industrial equipment and in many engineering applications like design calculations, mass transfer, heat flow etc. The experimental vapor-liquid equilibrium data of mixtures are extremely important in designing separation equipment. Excess molar enthalpy data are required for the design of heaters, coolers, condensers etc. and also for the removal or supply of heat to chemical reactions. Densities of vapour and liquid phases are important to give a proper size in the process design of many separation equipments. Speeds of sound data and derived Acoustic properties are used in industries for the design of industrial plants, pipelines and pumps etc. It is, therefore, necessary to have access to reliable data on thermodynamic properties of multicomponent liquid mixtures (components differing in size, shape and polarity). Thermodynamic properties of binary mixtures have generated a vast literature and workers have utilized the observed data (i) to obtain information about the state of components in pure and mixed state along with nature and extent of interactions existing in mixtures; and (ii) for the development of theories /molecular models describing the thermodynamic behavior of liquid
