Resumen:
Binary diffusion coefficients at infinite dilution in supercritical carbon dioxide, DAB, have been measured for the four monohalogenated benzenes (fluorobenzene, chlorobenzene, bromobenzene and iodobenzene) with the Taylor-Aris technique in a chromatographic apparatus as a function of temperature and pressure. The ranges covered for these two variables were 313-333 K and 15.0-35.0 MPa, respectively. As the four solutes are similar molecules, the Corresponding States Principle (CSP) has been tested, together with the results of several predictive equations.
