Table 11. Self-Diffusion Coefficient of Liquid Sulfolane as a Function of Temperature as Predicted from This Work, D.
| temperature/K | D/10–11·m2·s–1a,b |
|---|---|
| 303 | 11.89 ± 0.4 |
| 323 | 22.33 ± 0.5 |
| 348 | 40.83 ± 0.7 |
| 373 | 65.77 ± 1.2 |
| 398 | 103.38 ± 1.3 |
The expanded uncertainty (U) is reported at 95% level of confidence.
The data follows an exponential fit of the form: D = A e–Ea/kBT. Where activation energy Ea = 22.60 kJ·mol–1 and A = 97372.59 × 10–11·m2·s–1.
