Example 5.1-3: Diffusion in supercritical carbon dioxide Carbon dioxide, above its crit- ical point, may become an important industrial solvent because it is cheap, nontoxic, and nonexplosive. Estimate the diffusion of iodine in carbon dioxide at 0C and 33 atmos- pheres. The diffusion coefficient measured under these conditions is 7. 104 cm/sec. Solution The binary diffusion coefficient at 0C and 1 atmosphere can be found from Eq. 5.1-1: Chapman-Enskog
