摘要
Densities of the binary systems of m-xylene with ethyl acrylate, butyl acrylate, methyl methacrylate, and styrene have been measured as a function of composition, at 298.15 K 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 m-xylene with methyl methacrylate, ethyl acrylate, and styrene. The excess volumes for the m-xylene+butyl acrylate system are positive for solvent (m-xylene) concentrations below 0.3 mole fraction and negative above this concentration.
