Abstract

Densities of the binary systems of p-xylene with ethyl acrylate, butyl acrylate, methyl methacrylate, and styrene have been measured as a function of the composition at 298.15K and atmospheric pressure, using 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 binaries of p-xylene with methyl methacrylate and styrene and negative for the binary with butyl methacrylate. The excess volumes for the system p-xylene+ethyl acrylate are positive for p-xylene concentrations less than 0.7 mole fraction and negative afterwards. The values of the excess volume for the systems of p-xylene with ethyl acrylate and styrene are small enough to assume that they behave ideally.
