چکیده انگلیسی
The Taylor–Aris chromatographic technique was employed for the determination of the diffusion coefficients of phenylmethanol, 1-phenylethanol, 2-phenylethanol, 2-phenyl-1-propanol, and 3-phenyl-1-propanol at infinite dilution in supercritical carbon dioxide from 313.16 to 333.16 K and pressures between 15.0 and 35.0 MPa. Diffusivities were correlated with temperature, pressure, solvent density and solvent viscosity, and 12 predictive equations were compared with experimental data: Wilke–Chang, Lusis–Ratcliff, Tyn–Calus, Kooijman, Lai–Tan, Catchpole–King, Eaton–Akgerman, He, He–Yu, Liu–Silva–Macedo, Dariva–Coelho–Oliveira, and Rah–Kwak–Eu–Laffleur. Considerations regarding the diffusion coefficients of the isomers were also made.
