Viscosity and Density of Methane + Methylcyclohexane from (323 to 423) K and Pressures to 140 MPa

A new apparatus is described for measuring phase behavior and flow properties of water and/or hydrocarbon systems from ambient conditions to pressures of 140 MPa and temperatures to 474 K. Viscosity and density measurements have been made on pentane and decane and compared to the literature data. The measurements on pentane and decane have been made to 140 MPa and 423 K. Viscosity and density are reported for methane + methylcyclohexane at 25, 50, and 75 mass % methane, and at three temperatures, (323, 373, and 423) K, from saturation pressure to 140 MPa.
