Determination of experimental excess molar properties for MTBE+1-propanol+octane

Volumetric and Transport Properties of Binary Mixtures of n-Octane + Ethanol, + 1-Propanol, + 1-Butanol, and + 1-Pentanol from (293.15 to 323.15) K at Atmospheric Pressure

“…As mentioned before, several research groups have measured the density and excess molar volume of mixtures of n-octane with ethanol, 1-propanol, 1-butanol, and 1-pentanol. However, most of these measurements have been done at 298.15 K 27,28,[39][40][41]45,47,48,50,51,63 and at a maximum temperature of 318.15 K for the mixture of n-octane + ethanol. 38 Excess molar volumes have been measured by several authors.…”

“…In particular, different thermodynamic properties for the binary mixtures of n -octane with ethanol, 1-propanol, 1-butanol, and 1-pentanol have been reported in the literature at various temperatures. Densities for n -octane + ethanol have been measured at 298.15 K by Segade et al and Orge et al Later, Orge et al measured the densities at a wider temperature interval from (303.15 to 318.15) K. Feitosa et al measured them from (273.15 to 298.15) K with increments of 2.5 K. Density measurements for n -octane + 1-propanol at 298.15 K have been reported by Kaur et al, Iglesias et al, Orge et al, and Mato et al . Gupta et al measured the excess molar volume of this mixture at 303.15 K. Measurements from (293.15 to 308.15) K were performed by Jiménez et al , Densities for the system n -octane + 1-butanol have been measured by Nath at 293.15 K, by Gupta et al at 303 K, by Nath and Pandey at (288.15 and 298.15) K, by De Cominges et al from (288.15 to 308.15) K, and by Dubey et al from (298.15 to 308.15) K. Also, different authors have measured the density of this mixture at 298.15 K. ,,,,− For the mixture of n -octane + 1-pentanol, several authors ,,,, have measured the liquid density at 298.15 K. Gupta et al report the excess molar volume for the same mixture at 303.15 K.…”

Excess enthalpy, density, and speed of sound determination for the ternary mixture (methyl tert-butyl ether+1-butanol+n-hexane)

“…In earlier publications [6][7][8][9][10][11][12], volumetric, ultrasonic and calorimetric properties for binary and ternary system with these type of molecules were reported; and in a recent paper from our laboratory [13] experimental results for densities, speeds of sound, and others related properties for the ternary system {MTBE + 1-butanol + n-decane} were reported. Herein, as a continuation of earlier investigations, a similar study has been carried out for a homologous ternary mixture, where the third component involved is n-hexane.…”

Excess Molar Enthalpies of Ternary and Binary Mixtures Containing 2-Methoxy-2-Methylpropane, Ethanol, and Nonane

“…The lines of constant ternary excess molar enthalpy, H m,123 E , calculated using eq 4 are plotted in Figure 3a. Figure 3b represents the ternary contribution, x 1 x 2 (1 À x 1 À x 2 )Δ 123 , to the excess molar enthalpy correlated with eq 5. a Three experimental series of measurements were carried out for the ternary compositions resulting from adding nonane to a binary mixture composed This trend is also observed in the published ternary systems MTBE + propanol + alkane (hexane, 9,18 octane, 8,17 nonane, 2 decane 3 ) and MTBE + pentanol + alkane (octane, 5 nonane, 10 decane 11 ).…”
