Refractive properties of binary mixtures containing 2-methoxyethanol and n-butylamine, isobutylamine, sec-butylamine and tert-butylamine
2003
Refractive index (n) and related properties such as molar refraction (R) have been investigated for 2-methoxyethanol (ME) + n-butylamine (n-BA) and 2-methoxyethanol (ME) + isobutylamine (iso-BA), 2-methoxyethanol (ME) + sec-butylamine (sec-BA) and 2-methoxyethanol (ME) + tert-butylamine (tert-BA) binary mixtures over the entire composition range, at different temperatures in the range 291.15 ≤ T/K ≤ 313.15. Furthermore, the excess molar refraction (RE ) and deviation from ideality refractive index (Δn) have been examined, in order to identify the presence of intermolecular complexes in these binary liquid mixtures. The results obtained have been interpreted on the basis of specific intermolecular interactions between species.
