Abstract: | Densities of the ternary system, ethylbenzene + styrene + ethyl acrylate, 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 system, ethylbenzene + ethyl acrylate, and negative for the systems
ethylbenzene + styrene and styrene + ethyl acrylate. The corresponding data were correlated with the Redlich-Kister equation
and with a series of Legendre polynomials. Several models were used to correlate the ternary behavior from the excess molar
volume data of their constituent binaries and were found to fit the data equally well. The best fit was based on a direct
approach, without information on the component binary systems. |
