Diffusion coefficients
The correlation proposed by Lapuerta et al. [25] for the determination
of the diffusion coefficients of alcohols in their binary alcohol–air
gaseous mixtures at reduced pressure, was used (Eq. (2)),
with n being the carbon number of the alcohols. Results showed
that diffusion coefficients are higher as carbon chain length
decreases, as shown in Fig. 2.
