A new flow apparatus for high-pressure vapour-liquid equilibrium measurements was assembled. Its main feature is the use of a static mixer followed by a cyclone separator. Phase equilibrium ratios were determined, at 323.2 K and at pressures up to the vicinity of the mixture critical pressure, for the following systems: carbon dioxide + limonene, carbon dioxide + citral, carbon dioxide + linalool, carbon dioxide + limonene + citral and carbon dioxide + limonene + linalool. The results compare well with available literature data. (C) 2002 Elsevier Science B.V. All rights reserved.
