Abstract
The alkyl or alkanol amines are widely used as absorbent for CO2 capture owing to interaction between
amines and CO2. In order to increase the CO2 loading in amine based absorbents, blending of amine
with alkanol may be one option. As thermophysical properties of of utmost importance in designing,
in present work, the refractive index of dibutylamine (DBA) and isomeric butanol as well as their
binary mixtures at 298.15 K to 308.15 K were measured. The Δn are found positive for DBA + isomeric
butanol mixtures. The Δn values were correlated with Redlich-Kister polynomial. The refractive index
data were also predicted by various correlations and results were expressed in terms of standard
deviation. The Δn values were also employed to calculate the excess molar volume of the present
binary mixtures. Further Δn data analysed in terms of intermolecular interaction among DBA (1) +
isomeric butanol (2) mixtures.
