The energies of activation of the interaction of alkanols and alkanediols with dipalmitoyl phosphatidylethanol amine monolayers spread at the air/water interface were estimated from the increase in the surface pressure with the concentration of the injected alcohol. The energies of activation are linear functions of the chain length of the injected alkanol for the one‐, two‐, three‐, six‐, and eight‐carbon chains and of the alkanediols for the two‐, three‐ and six‐carbon chains. The plots of the data that exist in the literature of the reflection coefficients of these alkanols and alkanediols against the chain length obtained in biological membranes present similar linearities.
