Thermodynamic study of (alkyl esters + α,ω-alkyl dihalides) I: HmE and VmE for 25 binary mixtures {xCu − 1H2u − 1CO2C2H5 + (1 − x)α,ω-ClCH2(CH2)v − 2CH2Cl}, where u = 1 to 5, α = 1 and v = ω = 2 to 6

The application of two versions of the UNIFAC group contribution models produces no good estimations of HmE.
