Volumetric properties of 1,2-dimethylbenzene+ethyl acrylate, butyl acrylate, methyl methacrylate, and styrene at 298.15 K

Densities of the binary systems of 1,2-dimethylbenzene with ethyl acrylate (EA), butyl acrylate (BA), methyl methacrylate (MMA), and styrene have been measured as a function of the composition, at 298.15 K and atmospheric pressure, using an Anton Paar DMA 5000 oscillating U-tube densimeter. The calculated excess volumes (VE) were correlated with the Redlich–Kister equation. The excess volumes are positive for the binaries of o-xylene with MMA and styrene, and negative for o-xylene+butyl acrylate. All systems present small deviations from ideality; the system o-xylene+ethyl acrylate is closest to ideality.
