Partial molal expansibilities of organic compounds in aqueous solution. I. Alcohols and ethers

Apparent molar heat capacities of aqueous solutions of 1-propanol, butane-1,4-diol, and hexane-1,6-diol at temperatures from 300 K to 525 K and a pressure of 28 MPa

“…A simultaneous fit to the results of Makhatadze and Privalov, Alexander, Nakajima et al, (18) and Friedman and Scheraga (19) gave similar results (maximum difference in DC p,m = 4 J·K −1 ·mol −1 ). When the dilatometric results of Cabani et al (20) (with the third derivative set to zero) are used to calculate DC p,m for ethanol and propanol, the results are systematically lower by ( It was found that a quadratic function of temperature was adequate to fit the experimental temperature dependence of the functional group parameters C j . The resulting equation for predicting C a p,2 was: Table 8 gives the functional group parameters resulting from a weighted least-squares fit of equation (11) to the values of C a p,2 in tables 6 and 7.…”

Volumetric properties of (water + diethanolamine) systems

“…We (1 1, 15) and others (9,10,13,16,17) have used partial molar volumes (V20) of many organics in water to develop additivity schemes that might contribute to our understanding of organic-water interactions and that are certainly useful for predicting partial molar volumes for organic solutes in water. f few of these investigations (especially ref.…”

Density and excess molar volumes of aqueous solutions of morpholine and methylmorpholine at temperatures from 298.15 K to 353.15 K

“…b To whom correspondence should be addressed. (16) cyclic ethers, (17) and apparent molal heat capacities (18) of these compounds at low concentrations in water. We have measured the densities of the aqueous mixtures of these two compounds at temperatures from 298.15 K to 353.15 K covering the full range of concentrations.…”
