Tracer diffusion coefficients of citral and d-limonene in supercritical carbon dioxide

Binary diffusion coefficients of α-pinene and β-pinene in supercritical carbon dioxide

“…On the other hand, it is important to emphasise that the molar volumes at normal boiling point were estimated, which obviously introduces additional errors. In previous works [17,27,29], the authors published tracer diffusivities of diethyl ether, diisopropyl ether, tetrahydrofuran, citral, d-limonene, linalool and benzene in supercritical carbon dioxide. Using the data points at 12 MPa, for instance, it is possible to confirm that indeed there exists an inverse relation between D 12 and the molar volume of the solute at its normal boiling point.…”

Impulse response techniques to measure binary diffusion coefficients under supercritical conditions

“…(1) In carbon dioxide by the Taylor dispersion method [3,[16][17][18][19][20][21]24,25,27,28,[30][31][32][33]47,51,52,55,56,58,60,64,[66][67][68][69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84][85]. (2) In carbon dioxide by the modified Taylor dispersion method [13].…”

Diffusion coefficients in ethanol and in water at 298K: Linear free energy relationships

“…In a further study, Chan et al [39] measured the diffusion coefficients of aromatic compounds, containing one polar group, in acetone at 298.2 K, using the Taylor dispersion method [42][43][44][45]. Again, a linear relationship was found between V W and 1/D 12 for the non-associated pseudo-planar solutes.…”

“…The diffusion experiments of Chen and Chan [39] were designed to probe the effects of hydrogen bonding. In this work, Chen and Chan measured diffusion coefficients, of aromatic solutes containing one polar functional group in ethanol at 298.2 K, using the Taylor [42][43][44][45] dispersion method. The solutes studied are all pseudoplanar in shape.…”
