FTIR and thermodynamic study of Pakistani and international crude oils in 1,4-dioxane

ABSTRACT

This paper is the continuation of our previous paper, which concerned the viscosity of crude oils in 1,4-dioxane. In this paper, we present the Fourier Transform Infrared (FTIR) spectroscopy and thermodynamic study of Pakistani and International crude oils. Degree of branching, chain length, and degree of substitution in aromatic by FTIR data were calculated. Thermodynamic parameters viz., energy of activation (E_η), free energy change of activation (ΔG^*), latent heat of vaporization (L_v), and entropy change of activation (ΔS^*) have also been evaluated.
