Abstract
Excess volumes have been measured by means of a continuous-dilution dilatometer for [(1 - x )C 6 H 5 CH 2 CN + x {C 6 H 6 or C 6 H 5 CH 3 or o -(CH 3 ) 2 C 6 H 4 or m -(CH 3 ) 2 C 6 H 4 or p -(CH 3 ) 2 C 6 H 4 or C 6 H 5 C 2 H 5 or C 6 H 5 CH:CH 2 }] at the temperature 298.15 K. Values of V m are negative over the entire range of composition for all mixtures. | V m (minimum)| and | V m ( x = 0.5)| values of this series decrease in the sequence: C 6 H 5 CH 3 > C 6 H 5 CH 2 CH 3 > p -C 6 H 4 (CH 3 ) 2 > m -C 6 H 4 (CH 3 ) 2 > o -C 6 H 4 (CH 3 ) 2 > C 6 H 5 CH:CH 2 > C 6 H 6 . The results shows that there are quite strong interactions between nitrile molecules and aromatic-hydrocarbon molecules.
