β¦ Synopsis
Excess molar volumes of (butan-1-ol, or butan-2-ol, or 2-methylpropan-1-ol, or 2-methylpropan-2-ol + benzene, or toluene) over the entire range of composition have been measured dilatometrically at the temperature 308.15 K. The results indicate that the branching of an alkyl group of butanol near the hydroxyl group makes both the hydrogen bonding and the electron donor-acceptor interactions between butanol and benzene or toluene molecules less effective.

Excess molar volumes V E m and excess molar heat capacities C E p,m were determined for mixtures of benzonitrile with chlorobenzene, or benzene, or toluene at the temperatures 298.15 K and 303.15 K. For all the systems the values of V E m were negative over the whole range of compositions and values
