Density of organic binary mixtures from equilibrium measurements Academic Article uri icon


  • Abstract A reduction model for equilibrium measurements data (pressure–temperature– weight data) was developed. The model allows indirect measurements of the refrigerant concentration at the liquid and the gas phases and the solution density. The reduction model was validated by both comparing the obtained pressure–temperature–concentration relation at equilibrium conditions and solution densities with experimentally direct measurements carried out by Kriebel and Loffler [M. Kriebel, J. Loffler, Therodynamische eigenschaften des binary systems difluormono-chlormethan (R22)–tetraäthylenglykoldimethyläther (E181), Kältetechnik 17 (1965) 266–271](up to 80° C) and by us (up to 120° C) over a wide range of pressure and temperature.
