- ItemApparent molar heat capacities of aqueous solutions of acetic, propanoic and succinic acids, sodium acetate and sodium propanoate from 300 to 525 K and a pressure of 28 MPa(1996) Inglese, Americo; Šedlbauer, Josef; Wood, Robert H.The apparent molar heat capacities of dilute aqueous solutions of acetic, propanoic and succinic acid and sodium salts of the two monofunctional acids were measured at 300 K < T < 525 K and p = 28 MPa. Corrections for ionization/ hydrolysis and relaxation effects were applied and the results were extrapolated to infinite dilution to calculate Cop.2. After subtracting the heat capacity of a point mass, the remaining heat capacity was successfully decomposed into functional group contributions at all temperatures. Together with the results of our previous paper on alcohols and dials(2) the heat capacity contributions of the CH2, CW3, OH, COOH, (COOH)2, and COONa groups are now available and these allow reasonably accurate predictions of the heat capacities of all compounds composed of these groups in this temperature range.
- ItemApparent molar heat capacities of aqueous solutions of phosphoric acid and sulfur dioxide from 303 to 623 K and a pressure of 28 MPa(Plenum Publ Corp, 1997) Sharygin, Andrei V.; Inglese, Americo; Šedlbauer, Josef; Wood, Robert H.Heat capacities of aqueous solutions of phosphoric acid from 0.1 to 0.8 mol- kg-1 and sulfur dioxide from 0.2 to 0.9 mol-kg-1 have been measured with a flow heat-capacity calorimeter from 303 to 623 K and a pressure of 28 MPa. At the lowest molality single-solute solutions as well as mixtures of either H3PO4 or SO2 with HC1 were measured to repress dissociation. Calculated apparent molar heat capacities were corrected for dissociation reactions and the chemical relaxation effect. Experimental results for mixtures were analyzed using Young’s rule. Standard state partial molar heat capacities of H3PO4(aq) and SO2(aq) were obtained by extrapolation to infinite dilution. A few measurements of the densities of aqueous H3PO4 and SO2 were made at 25°C and a pressure of 28 MPa.
- ItemApparent molar heat capacities of aqueous solutions of propylamine, 1,4-butanediamine, 1,6-hexanediamine, propylamine hydrochloride, propionamide, pyridine, and sodium benzenesulfonate at temperatures from 300 K to 525 K and a pressure of 28 MPa(Academic Press Ltd, 1997) Inglese, Americo; Šedlbauer, Josef; Yezdimer, Eric M.; Wood, Robert H.The apparent molar heat capacities of dilute aqueous solutions of propylamine, 1,4-butanediamine, 1,6-hexanediamine, propylamine hydrochloride, propionamide, pyridine, and sodium benzenesulfonate were measured at 300 K
