Title : Volumetric, optic and acoustic properties for binary mixtures of 2-(2- ethoxyethoxy)ethanol with 1-propanol, 2-propanol, 1-butanol or 2-butanol at temperature range of (293.15 to 323.15) k
Abstract:
The 2-(2-Ethoxyethoxy)ethanol is widely employed in numerous industries, including detergent, cosmetic, pharmaceutical, food and petrochemical industries. The selected alcohols are generally used as solvents for an extensive range of chemical and textile processes, in organic synthesis and as a chemical intermediate. They are also used as paint thinner and solvents in other coating applications where they are used as relatively slow evaporating latent solvents in lacquers. Other uses of these compounds are as surfactants, additives in detergents and agriculture products. It is of great importance to understand the mixing behaviour of alkoxyethanols mixtures. In order to understand and obtain an overall picture, these binary mixtures were studied at a whole composition range. As a continuation of our general program of research concerning the thermodynamic and thermophysical properties of binary mixtures containing alkoxyalcohols, we present here experimental results of vapor–liquid equilibria (VLE) data, densities, sound velocity and the refractive index for the binary liquid mixtures containing {2-(2-Ethoxyethoxy)ethanol (1) + 1- propanol (2), + 2-propanol (2), + 1-butanol(2), or + 2-butanol (2)}. The excess/derived functions from such data have been interpreted with regards to the different sizes of molecules and the strength of specific and non-specific intermolecular interfaces occurring between components of the mixture.
