Rezumat:

Excess Gibbs energies, GE, for ten binary systems containing nitromethane or nitroethane + 1-chlorobutane, + 1-chloropentane, + 1,2-dichloroethane, +1,3-dichloropropane, and + 1,4-dichlorobutane are interpreted in terms of the DISQUAC group contribution model. The systems are characterized by three types of contact surface: nitro (NO2), chloro (Cl) and alkane. The interchange energy parameters of the alkane/NO2 and alkane/Cl contacts were determined independently from the study of alkane + nitroalkane and alkane + chloroalkane systems. The structure-dependent interchange parameters of the NO2/Cl contact are report in this work. The model provides a fairly consistent thermodynamic description of the investigated mixtures
