ABSTRACT; Supercritical fluid technology is an area of rapid development, but there is still a lack of fundamental data available. In the design of supercritical processes, thermodynamic and transport properties are both relevant. In order to evaluate the importance of external mass transfer in packed beds binary diffusion coefficients of solutes in the supercritical fluid are essential.
In this paper experimental data for binary diffusion coefficients in supercritical carbon dioxide DAB are reported. Solutes were chosen for
\u2022 Creating a large data base of diffusion coefficients data for the purpose of developing a semiempirical correlation on the basis of the chemical structure;
\u2022 Their importance for some specific industry (in particular food and fragrance industries).
As a consequence different aromatics and some terpenes (Linalool, Citronellol, Terpineol, Nerol, Geraniol) are considered.
Peak broadening technique was used for the experimental determination. The effects of temperature and pressure were evaluated in the range 40-60 \ub0C and between 150-300 bar
