ABSTRACT

Densities of the ternary system toluene + butyl acrylate + methyl methacrylate and its three binaries have been measured in the whole composition range, at 298.15 K and atmospheric pressure using an Anton Paar DMA 5000 oscillating U-tube densimeter. The calculated excess molar volumes are positive for the binary systems toluene + methyl methacrylate and butyl acrylate + methyl methacrylate and negative for the system toluene + butyl acrylate. The corresponding data were correlated with the Redlich Kister equation and with a series of Legendre polynomials. Several empirical equations were used to correlate the ternary behavior from the excess molar volume data of their constituent binaries and were found equally good to fit the data. The best fit was based on a direct approach, without information on the component binary systems.
