Excess functions atT= 298.15 K of (butanenitrile +methanol, +pentan-1-ol, +heptan-1-ol, +nonan-1-ol, or +decan-1-ol)

Excess molar enthalpies and excess molar volumes of (an alkanol + a nitrile compound) atT= 298.15 K andp= 0.1 MPa

“…The H E m for (an alkanol + butanenitrile) at T = 298.15 K where the alkanol is methanol, or 1-propanol, or 2-propanol, or 2-butanol, or 1-pentanol, or 1-hexanol, or 1-heptanol, or 1-octanol or 1-nonanol, or 1-decanol have been measured by Garriga et al (20)(21)(22)(23) The H E m results of this work and those of Garriga et al (20,21) for (methanol, or 1-propanol + butanenitrile) agree to within ±2.5 per cent in the worst case.…”

“…The ERAS model parameters characteristic of the mixtures of this work are presented in table 7. These parameters are: K AB , the association constant for compound A (20) , Garriga et al; (21) , Garriga et al; (22) ×, this work. ----, NC(CH 2 ) 4 CN; --, CH 3 (CH 2 ) 2 CN;…”

Thermodynamics of mixtures containing a very strongly polar compound. 11. 1-Alkanol+alkanenitrile systems

“…On the basis of such features, one can conclude that interactions in the investigated systems are essentially of dipolar type. 1-Alkanol + alkane mixtures, characterized by alcohol selfassociation, show large and positive isobaric excess heat capacities, C E p;m , (11.7 J mol À1 K À1 for ethanol + heptane [43]), and large and [72]. Solid lines, DISQUAC calculations with interaction parameters listed in Table 1.…”

Thermodynamic excess properties for binary mixtures of (butanenitrile + a carboxylic acid) atT= 298.15 K

“…Endothermic effects were observed for (butanenitrile + ethanol, or butan-1-ol) by Garriga et al, (5) for (butanenitrile + propan-1-ol, or propan-2-ol) by Garriga et al, (6) for (butanenitrile + methanol, + pentan-1-ol, + heptan-1-ol, + nonan-1-ol, or decan-1-ol) by Garriga et al (7) and, for (acetic and its methyl-substituted acids + acetonitrile) by Lark and Banipal. (8) The results obtained in this work were interpreted in terms of association of the acids, dipole-dipole interactions between heteromolecules and the steric hindrance caused by the increased methylation.…”
