Abstract
Selfdiffusion coefficients determined by the NMR spin-echo technique are reported for n-octane (-25–75°C, 0·1–361 MPa) and toluene (-50–50°C, 0·1–369 MPa). In the case of toluene, these are supplemented at 25°C by 14C radiotracer diaphragm cell measurements. The results for each substance are correlated with high pressure viscosity data. Those for toluene overlap the range of applicability of the rough hard sphere model, and this model is used to compare the transport properties of toluene with those of benzene and mesitylene.Keywords
