Ultrasonic and13C N.M.R. studies of isomeric octanols

Abstract: Ultrasonic and 13C N.M.R. data are reported for l-octanol, 2-octanol, 2,3-dimethyl-3-hexanol and 2,4-dimethyl-3-hexanol. The ultrasonic relaxation data indicate that in 1-and 2-octanol the observed dispersion can be attributed to hydrogen bond exchange processes associated with structural relaxation of the liquid. For 2,3-dimethyl-3-hexanol and 2,4-dimethyl-3-hexanol, an additional contribution associated with internal rotational relaxational processes has been detected. Assignments of the observed 13C spectra… Show more

“…The role played by the strength of H-bonding in the structure and stability of local aggregates of n -alcohols has been recognized for a long time. It has also been established that the strength of this intermolecular interaction inversely scales with the length of the alkylic chain. More stable aggregates are found in alcohols with a shorter alkylic tail, and the bond forces due to the O−H group interactions prevail over those of the hydrocarbon chain.…”

“…The strength of the hydrogen bond interactions, the degree of self-association, and the geometrical arrangements of local environments in the liquid state are in some way correlated with the length and branching of the hydrocarbon tail and with the different exposure of the OH group. The same molecular factors also regulate relaxation processes and dynamical properties of the liquid systems. In amphiphilic molecules, two types of forces take part in determining overall liquid organization, namely, the dispersion forces concentrated on the hydrocarbon tails (i.e., “hydrophobic”) and the dipolar electrostatic ones localized on the OH groups (i.e., “hydrophilic”). These forces are correlated, and their interplay, determining the structure and the dynamics of the liquid at molecular scales, modulates its macroscopic properties.…”
