Evaluation of the carboxylatechlorine interaction parameters using the DISQUAC group contribution model

Thermodynamic behaviour of the eight systems containing 1,1,2,2-tetrachloroethane and ethyl or propyl C1C4 alkanoates was interpreted in terms of the DISQUAC group contribution model. The DISQUAC dispersive interaction parameters for COOCl contact were evaluated considering the quasichemical parameters are equal to zero. The molar excess Gibbs energies and the excess enthalpies were calculated using this model and compared with experimental data. The relation between the DISQUAC interaction parameters for COOCl contact and the chain length of the alkanoate was established.
