Dielectric constants, densities, and viscosities of acetone-1-propanol and acetone-n-hexane mixtures at 25.deg.C

Abstract: man and Scheraga (5) carried out pycnometric density determinations on some of the compounds in a higher concentration range (m > 0.1). In both cases, linear " extrapolations, based on measurements at only five concentrations, were performed to evaluate V §. The agreement between the literature values of V°and those obtained in this study is reasonable, but this is not true for the slopes of the ( ) isotherms, as is shown in Table V.Unfortunately, Friedman and Scherega state neither the numerical values of do … Show more

“…The adsorption of gas‐phase modifiers induces a molecular microenvironment at the individual residue level which is more akin to the solution phase where solvent‐exposed residues are solvated by polar molecules which form a solvation shell. This change in molecular environment correlates with differences in relative permittivity at 25°C between nitrogen gas (~1.0) and the gas‐phase modifiers (i.e., 32.7 for methanol, 37.5 for acetonitrile, and 20.7 for acetone). Despite these values being lower than that for water (78.4), residues with adsorbed modifier molecules experience a radically different local electrostatic environment compared with the absence of modifiers.…”

“…Graphs of dielectric constant (e) vs. solvent mole fraction for representative binary systems containing acetone are shown in Figure 1. Nonlinear functions are observed not only for those systems having a strong hydrogen bond donor (i.e., water and 1-propanol) but also for the cases of the nonpolar hydrocarbons, n-hexane and benzene (16,17). For the HBD systems, the pronounced curvature would be expected to arise from both donor-acceptor interactions involving hydrogen bonding to acetone and disruption of the structure of the self-associated hydroxylic solvent by the added acetone (17).…”
