摘要:
An experimental study of the vapour pressure, and other physical properties, of an ideal system is described. Raoult's law is followed closely by benzene up to high concentrations of naphthalene. Such behaviour may be connected with the smallness of the dipole moments, although that of naphthalene is far from zero. Other physical properties investigated, viz., density, viscosity, and surface tension, show fairly close, but not exact, additive behaviour. In this respect, the behaviour is very similar to that of a system previously investigated, naphthalene–p-nitrophenol, where, however, the partial pressures show marked deviation from Raoult's law: this is in harmony with the (presumed) high electric moment ofp-nitrophenol. It appears, in so far as the two systems studied are concerned, that marked deviation from Raoult's law may be associated with high dipole moment, but that this deviation does not necessarily cause any marked deviation from additivity in other physical properties not dependent on vapour pressure.
