The heat capacities, volumes, and expansibilities of tert-butyl alcohol – water mixtures from 6 to 65 °C

Abstract: . Can. J. Chem. 55,856 (1977). The densities and specific neat capacities of niixtures of terr-butyl alcohol (TBA) and water (W) have been measured at 6,10, 25, 40, 55, and 65 'C. From these data the apparent lnolal volilmes (O,), heat capacities j&), and expansibilities (4,) were evaluated. Generally, the tenlperature dependence of these quantities is rather characteristic of hydrophobic solutes in water. At high co~lcentrations 6, and 4,. resemble those of surfactants, suggesting the existence of some microp… Show more

“…Examples of such non-ideal behavior in the binary mixture of water and amphiphilic solutes are varied and well-studied [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Sometimes the anomaly is strongest at surprisingly low solute concentrations.…”

“…Recent work in this laboratory (1)(2)(3) has been concerned with transitions in aqueous liquid mixtures. Through heat capacity measure~nents the apparent rnolai heat capacity 4, of many simple liquids which are completely miscible in water, such as din~ethylformalnide (4), dirnetkylsulfoxide (51, and dioxane (6), decreases in a regular way from the standard (infinite dilution) partial molal heat capacity, 4,' = C,' , to the molar heat capacity of the pure organic liquid CP0.…”

“…A small, almost negligible, correction was applied to the H30 mixtures at low concentrations of TBA have attracted measured value of Ah to obtain the value at the unified -much attention, and there are numerous thermodynamic data I available in the literature (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14). Of these, the quantities I proportional to the second derivatives of the free energy with 1 respect to appropriate variables appear to show more pronounced features.…”

“…Of these, the quantities I proportional to the second derivatives of the free energy with 1 respect to appropriate variables appear to show more pronounced features. Examples include the concentration fluctuations (5-7), thecompressibility (8,9, 1 1), the expansibility (lo, 12), the heat capacity (10,12), and the partial molar volume (10,13). While the integral heats of mixing have been ~ determined and compiled (14), it is surprising that there appears to be no actual measurement of the differential heats of dilution in the literature.…”
