Volumetric and FT-IR Studies of the Binary Liquid Mixtures of Tributylamine and Alkyl Ester (C₁–C₅)

Abstract

Herein, physicochemical functions were obtained using the density (ρ) and speed of sound (u) data of tributylamine (TBA) + alkyl acetate (C1–C5) mixtures at a pressure of 101.325 kPa and at five different temperatures (293.15–313.15 K). An Anton Paar DSA 5000 M was used to determine the values of density (ρ) and speeds of sound (u) of the pure components and respective binary mixtures. It has been found that the function obtained from the density (V m E ) is positive and that from speeds of sound (uE ) is negative at all concentrations and at 293.15–313.15 K, which show that the presence of weak intermolecular interactions (dipole–dipole type) is also supported by FT-IR studies. The results obtained for V m E experimentally and theoretically (PFP theory) were correlated with each other.

“…Compared to pure PMM and pristine c‐CNT, FT‐IR spectrum of PMM/c‐CNT in Figure 2e exhibited a new peak at 1745 cm −1 associated with ‐COO groups and disappeared O‐H vibrational peak of PMM, suggesting the formation of ester bonds between terminal hydroxyl groups of PMM and carboxyl groups of c‐CNT. [ 36,37 ] Additionally, the characteristic Si‐O‐Si peak at 1050 cm −1 [ 38,39 ] for pure µSi and µSi/PMM can be observed in enlarged FT‐IR spectrum (Figure S4, Supporting Information), suggesting the existence of SiMP in µSi/PMM. However, the Si–Si peak at 493 cm −1 [ 38 ] for µSi/PMM was covered by the wide and strong peak at 603 cm −1 of PMM (Figure 2e).…”
