Résumé 0

"In a previous paper the interfacial entropy of tert-butyl-alcohol (TBA) at a heptane/water interface was evaluated using a du Noüy ring (Vásquez et al., 2002). Here, this problem is revisited using a more accurate instrument for interfacial measurements: the spinning drop tensiometer. The results differ considerably from the previous evaluations. A broad continuous distribution of interfacial entropy with a large maximum at a molar fraction of TBA (xTBA)= 0.01 is found. The height of the maximum and the concentration of TBA at which it occurs are similar to the ones exhibited by aqueous solutions of alcohol"
