Densities and excess volumes of binary mixtures of 1,4-dioxane with either ethyl acrylate, or butyl acrylate, or methyl methacrylate, or styrene at T=298.15 K

Abstract

Densities of binary mixtures of 1,4-dioxane with either ethyl acrylate, or butyl acrylate, or methyl methacrylate, or styrene have been measured as a function of composition at T=298.15 K and atmospheric pressure with an Anton Paar DMA 5000 oscillating U-tube densimeter. The calculated excess volumes were correlated with the Redlich–Kister equation and with a series of Legendre polynomials. The excess volumes are positive for the mixtures of 1,4-dioxane with methyl methacrylate and butyl acrylate and negative for the mixtures of 1,4-dioxane and styrene. The excess volumes for the system 1,4-dioxane and ethyl acrylate are negative for mole fractions x of 1,4-dioxane less than or equal to about 0.44 and positive at x greater than about 0.4498 and positive thereafter.
