“…Negative H m E values reflect the existence of strong interactions during the mixing process. This trend can be explained by the predominance of attractive forces between different molecules through dipole–dipole and hydrogen bonding leading to complex formation. ,, Positive H m E values can be interpreted by the preponderance of dissociation of the aggregates formed in the pure state (alcohols through hydrogen bonding and N , N -dimethylacetamide through dipole–dipole interaction). ,, It is noticed that secondary alcohols exhibit much higher H m E values than primary alcohols and that the H m E values increase with increasing alcohol chain length.…”

The surface tension at the liquid−air interface of eight binary mixtures formed by N,N-dimethylacetamide and n-alkanols (from methanol to 1-pentanol) or 2-alkanols (from 2-propanol to 2-pentanol) was studied at three different temperatures (283.15, 298.15, and 313.15 K) and a pressure of 0.1 MPa. Surface tension deviations were also calculated. Moreover, the excess molar enthalpies for all of these mixtures were measured at T = 298.15 K and a pressure of 0.1 MPa. Both deviation and excess functions were correlated with the mole fraction by means of the Redlich−Kister equation. The surface tension deviations are found to be positive for the system containing methanol, sigmoidal for ethanol and negative for the rest of the alkanols. With regard to excess molar enthalpies, negative values are found for the system containing methanol, sigmoidal values for ethanol, and positive values for the rest of the alkanols.

“…Recently, the use of isothermal calorimetry (ITC) for the generation of thermodynamic parameters has been (re-)evaluated and reported.

However, for studies on acid−amine interactions thermodynamic parameters obtained from ITC measurements appeared to be concentration dependent, restricting their use to the evaluated concentration range only.…”
