1H-NMR studies of the binary mixtures of sulfolane with ethylene glycol, diethylene glycol, triethylene glycol, and tetraethylene glycol at 303Â K

1H-NMR spectra in binary mixtures of sulfolane with ethylene glycol, diethylene glycol, triethylene glycol and tetraethylene glycol have been recorded over the whole composition range at 303 K under atmospheric pressure. The experimental data have been used to calculate the deviations in chemical shifts from the additive properties, viz. Δδ, as a function of mole fractions, and values obtained are fitted to the Redlich-Kister polynomial equation to obtain the binary coefficients and the standard errors. The results are discussed in terms of intermolecular interactions and structure of studied binary mixtures.
