X-ray Studies on Liquids: the Inner Peak for Alcohols and Acids

The Influence of Amphiphilic Substances on the Mutual Solubilities in Binary Liquid Systems (Microemulsions)

“…If such experiments are carried out close to the alcohol corner without surfactant, one finds a rather broad shallow maximum in the scattering curve at an angle corresponding to a Bragg d-value of about twice the length of the alcohol molecules. This has been interpreted [13] as being caused by quasi-lamellar aggregates of the alcohol molecules as schematically shown in Fig. 11a.…”

Development of the AVEC model for associating mixtures using NMR spectroscopy

“…The hydrogen bonds in the H F polymer configurations are among the strongest type of hydrogen bond known, with the energy of bond formation approximately 24-28 kJ/mol (Pimentel and McClellan, 1960). The results of X-ray diffraction studies (Warren, 1933;Pierce and MacMillan, 1938;Harvey, 1938Harvey, , 1939Wertz and Kruh, 1967;Narten et al, 1978;Narten and Sandler, 1979;Narten, 1979) on t-butyl alcohol and ethanol, infrared studies by the matrix isolation technique on methanol (Fox and Martin, 1940;Van Thiel et al, 1957;Bourderon et al, 1972;Luck, 1976), and the determination of average degree of association from viscosity measurements for the primary alcohols-methanol, ethanol, 1-propanol, and 1-butanol (Ratkovics et al, 1974)-can also be explained in terms of chain formation. The bond strength of the alcohol complexes is slightly weaker than the H F bond strength and is approximately 12-16 kJ/mol.…”

Supramolecular x-ray signature of susceptibility amplification in hydrogen-bonded liquids

“…Apart from 4M3H, with a mean alkyl branch length of l eff = 7.18Å [20], we study 2-butyl-1-octanol [(2B1O), l eff = 11.35Å], 2-hexyl-1-decanol [(2H1D), 13.85Å], and 2-decyl-1-tetradecanol [(2D1T), 18.85Å]. These MAs are structurally related to 2-ethyl-1-hexanol [(2E1H), 8.85Å], an alcohol supposed to form chainlike structures [10].…”
