Experimental results of density, viscosity, and refractive index at (298.15, 303.15, and 308.15) K and speed of sound at 298.15 K are measured for the binary mixtures of 1,4-dioxane with ethyl acetoacetate, diethyl oxalate, diethyl phthalate, and dioctyl phthalate over the entire range of mixture composition. From these data, excess molar volume, deviations in viscosity, molar refraction, speed of sound, and isentropic compressibility have been calculated. These results are fitted to the polynomial equation to derive the coefficients and standard errors. The experimental and calculated quantities are used to study the nature of mixing behaviors between mixture components. |
