Formation of a heteromolecular structure in aqueous solutions of ethanol and tetrahydrofuran

The formation of a heteromolecular structure in aqueous solutions of tetrahydrafuran is considered in the article. Changes in the permittivity of aqueous solutions of tetrahydrofuran over a wide range of concentrations (0÷1 molar fraction) were studied using the molecular dynamics method. It is shown that stable heteromolecular complexes in binary solutions are formed in the concentration range 0.3÷0.4 molar fractions. Extreme values of excess permittivity and excess refractive index of aqueous solutions are obtained.
