Molar isobaric heat capacities, C-pm, and molar excess isobaric heat capacities, C-pm(E), are reported for 1-butanol, 1-octanol or 1-decanol + benzylamine systems at (293.15, 308.15, 318.15, 333.15) K. C-pm(E) values were measured with a Setaram Micro DSC II microcalorimeter using a scanning method. The investigated mixtures are characterized by large and positive C-pm(E) (x(1) = 0.5) values at 298.15 K, which remarks that self-association and/or solvation effects are predominant in such solutions. The C-pm(E) curves are skewed towards higher mole fractions of the alcohol, which suggests that alcohol-amine interactions are more probable in that region. In addition, for a given 1-alkanol, C-pm(E) (x(1) = 0.5) decreases when temperature increases, due to alcohol dissociation is larger at elevated temperatures. The lower self-association of longer 1-alkanols and lower solvation effects may explain that the C-pm(E) (x(1) = 0.5) change with temperature is sharper for the solutions with the mentioned alcohols. The observed decrease of C-pm(E) (x(1) = 0.5) with the increasing of the chain length of the alcohol at enough high temperatures may be explained in similar terms. (C) 2014 Elsevier B.V.
