Excess molar volumes of (an alkanol + acetonitrile) at 298.15 and 308.15 K

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

“…Alternatively this effect could also be influenced by the increase in both the dimerization constants as well as increasing steric hindrance caused by additional methyl groups and resultant decrease in the association between butanenitrile and the carboxylic acid. This is further supported by the findings of Cibulka et al (16) who have shown that for binary systems containing alkanol and acetonitrile, V E increases in the order: V E (acetonitrile + normal alkanol) < V E (acetonitrile + branched alkanol) < V E (acetonitrile + secondary alkanol).…”

Excess volumes and excess enthalpies of acetic and its methyl-substituted acids + acetonitrile

“…The shifting of minimum to the acid poor region may be due to increase in both steric hindrance and dimerization constant. This is further supported by the findings of Cibulka et al (29) who have shown that for the binary systems containing alkanol and ACN, VE increases in the order…”

Excess molar volumes and partial molar volumes for (propionitrile+an alkanol) at T=298.15 K and p=0.1 MPa

“…Methanol and ethanol were first refluxed over Grignard reagent (Mg + I 2 ) for 6 h, with protection from the atmosphere and then distilled at atmospheric pressure [5,6]. The solvents 1-propanol, 2-propanol, and 1-butanol were dried with aluminum amalgam and then distilled [5,6]. 1-Pentanol was first dried with anhydrous calcium sulphate followed by distillation [5,6].…”

“…The alkanols were dried by distillation shortly before each set of experiments. Methanol and ethanol were first refluxed over Grignard reagent (Mg + I 2 ) for 6 h, with protection from the atmosphere and then distilled at atmospheric pressure [5,6]. The solvents 1-propanol, 2-propanol, and 1-butanol were dried with aluminum amalgam and then distilled [5,6].…”
