Molecular interactions in binary mixtures of 1-butoxy-2-propanol with alcohols at different temperatures: A thermophysical and spectroscopic approach

Composition-dependent association behavior in the mixture of isopropanol and trichloromethane: a volumetric, vibration spectroscopic and quantum chemical study

“…The purities of two solvents used were further ascertained via comparing their densities and refractive indices at T ¼ 298.15 K with the reported ones in the literature (Table S1 †). [22][23][24][25][26][27][28]…”

Densities and Excess Molar Volumes of the Ternary System (1,4-Dioxane + 2-Propanol + 1,1,2,2-Tetrachloroethane) at T = 288.15–318.15 K and at Atmospheric Pressure: Experimental Measurements and Prigogine–Flory–Patterson Modeling

“…The reduced volume, V ̃ i , of a constituent i is given by where the thermal expansion coefficient, α i , is defined by The characteristic pressure and volume, P i * and V i * , respectively, are defined by where the isothermal compressibility κ T i of a constituent i is given by The values of the parameters α i , V i * , and P i * for pure components were estimated from the Flory theory, whereas the thermal compressibility κ T i values were obtained using the equation The Newton–Laplace equation was used to estimate the isentropic compressibility values, κ S , for pure components The κ T i values for pure components were calculated using our experimental density values, ρ, whereas those of speed of sound, u i , and heat capacity, C p i , were calculated from the literature data. ,,,,− All the α i , κ T i , V i * , and P i * values, which were used in PFP calculation, are summarized in Table . The interchange parameter, χ 12 , was derived by fitting the V E expression (eq ) to our experimental V E values at T = 298.15 K. The adjusted values of χ 12 and the calculated three contributions to the V E values at equimolar fraction are reported in Table .…”

Acoustic, volumetric, transport and spectral studies of binary mixtures of 1-tert-butoxy-2-propanol with alcohols at different temperatures

“…The details of calibration of the instrument and the experimental procedure have been described elsewhere [19][20][21][22]. The speed of sound is measured using a propagation time technique.…”

“…The NMR chemical shifts of pure components and their molar equimolar mixture for 1 H were observed with a Bruker FT-NMR spectrometer operating at 300 MHz. Details of measuring procedure have been given in our earlier publication [20][21][22]. All the data analyses were performed in Microsoft Excel and Origin 6.1 software.…”

“…The FT-IR data are reported in Table S2 (given in Supplementary information) for all pure components and their equimolar concentration clearly shows that all the binary mixtures have a strong intermolecular interaction [20][21][22].…”
