Description
Summary:This study aims to investigate the physicochemical properties of 2-methoxyethanol (2-ME) and 2-ethoxyethanol (2-EE) in aqueous solutions of inositol at different concentrations and temperatures. The physical properties, of the solutions, including density (ρ), speed of sound (c), and spectroscopic properties, were measured to analyze the interactions between solutes and solvents. The study was conducted at a pressure of 0.1 MPa and four different temperatures (288.15, 298.15, 308.15, and 318.15) K, with a difference of 10 K between each temperature. The apparent molar properties and partial molar properties were obtained by using density and sound speed data to determine the solute–solvent interactions among the (2-ME/2-EE + water + inositol). The limiting apparent molar expansibilities (E ϕ 0) and its first-order derivatives (∂E ϕ 0/∂T)p were also calculated. The findings were analyzed to understand the hydrophilic–hydrophilic and hydrophilic–hydrophobic interactions within these systems. In addition, an FTIR spectroscopic study of a binary mixture (inositol and water) was conducted to provide further insights into the interactions between the solutes and solvents.
