Excess molar enthalpies of mixtures of pyrrolidin-2-one with methanol, or ethanol, or propan-1-ol, or butan-1-ol, or pentan-1-ol at the temperature 303.15K

Molar excess enthalpies of binary mixtures of [tributyl phosphate+{CH3(CH2)nOH (n=0 to 3)}] at 298.15K

“…It is well known that alcohol is association by H-bonding in pure state, in inert solvent, and in solvating solvent [14,15]. The enthalpies of association are about the same DH m ¼ Àð25 AE 2Þ kJ Á mol À1 [23] for several low molar mass alcohols, but the extent of association decrease as the length of the alkyl chain of the alcohols increases. TBP (dipole moment, 2.36 Debye) should associate by dipole-dipole interaction.…”

(Vapour+liquid) equilibrium in (N,N-dimethylacetamide+ethanol+water) at the temperature 313.15K

“…This is in contrast with the heat of mixing data: for the (amide + ethanol) mixtures the thermal effects are comparatively large. According to the literature data [16][17][18], the H E values at equimolar composition are: +599 J AE mol À1 for NMF, +486 J AE mol À1 for DMF, +195 J AE mol À1 for NMA, À74 J AE mol À1 for DMA, and +495 J AE mol À1 for 2PY (for NMP there are no data). Thus, we can draw two conclusions.…”

Excess Molar Enthalpies of Dibromomethane with Acetonitrile, Furan, Acetophenone and Tetrahydrofuran at T=313.15 K

“…The excess enthalpy results from the disruption of interactions between like molecules and the introduction of new interactions between unlike molecules [6]. indicate the presence of strong specific interaction leading to the formation of complexes.…”
