摘要: Abstract Experiments on thermodiffusion of binary organic solutions by the thermogravitational method are described. The separation curves discussed in connexion with “forgotten effect”. For nearly perfect solutions, Soret coefficient D′/D is independent composition. sign determined difference cohesion densities (energy vaporisation/molar volume) pure constituents. constituent higher density enriched at cold wall. A derivation this rule based elementary theory transport phenomena liquid phase given.
