High Pressure Densities of Mixtures of Coal Chemicals

Densities of seven coal chemicals (benzene, toluene, letralin, quinoline, m-cresol, bicyctohexyl and 1-methylnapthalene) and their binary mixtures at temperatures between 298 K and 338 K and pressures between 0.1 MPa and 34.5 MPa were measured using a high-pressure vibrating tube densitometer and are reported in this paper. The pure component densities were correlated using a modified Tail equation. The pure components were then used as reference fluids in a corresponding stales method for the prediction of the densities of the mixtures. @KEYWORDS High pressure Densities Mixtures Coal chemicals.
